2012 Top Truck Challenge Competitors: We Are The Champions Part 1

An In-Depth Look At Nine Of This Year’s Top Truck Champions’ Challenge Rigs

By: Ken Brubaker, Sean P. Holman, Photography by Four Wheeler Staff

To celebrate the 20th anniversary of the legendary Top Truck Challenge, we’ve invited all of the past champions of Top Truck to Hollister Hills, California, to compete in an unprecedented, history-making, weeklong mega-throwdown on seven of the gnarliest challenges known in the wheeling world. We’re calling it Top Truck Champions’ Challenge (TTCC), and it’s going to be incredible.

Since its inception in 1993, Top Truck has morphed considerably to adapt to the changing world of off-road competition. For example, we don’t waste time with the Show-n-Shine and the Ride-n-Drive any longer. Nowadays, Top Truck is lean and focused. Competitors at this year’s Top Truck Champions’ Challenge will compete in our seven famous events consisting of the Tow Test, Frame Twister, Mud Pit, Obstacle Course, Hill Climb, Mini Rubicon, and Tank Trap.

We didn’t put any stipulations on what the past champions can drive in TTCC. They can drive the rig they originally competed with or something completely different. What’s interesting is that the majority of TTCC competitors have chosen to drive their TTC-winning rigs. Others have created new rigs and some have even borrowed rigs.

Over the next several pages you can read a detailed overview of half of this year’s TTCC rigs (in no particular order) along with some comments from the drivers. The second half will publish next month in part two of “We Are The Champions,” so look for them in the November issue. Full coverage of all the TTCC action will follow in the December issue.

The most obvious change to Naeger’s rig since the last time we saw it in 2008 is the addition of 16.9-24 (52.8 inches actual height) BKT tractor tires. The meats are mounted on TrailReady 24-inch beadlock wheels with inner reinforcement rings. These tires are traction monsters, but slightly smaller in diameter than the 54-inch cut Boggers that Naeger ran in 2008. A Warn 9.5xp winch is at the ready in case the BKT’s get stopped cold in any of the events.

Name: Jeremy Naeger
Champion in: 2008
Driving: 2008 Avalanche buggy

In 2008, Jeremy Naeger, Bloomsdale, Missouri resident and president of Custom Differentials, tied with Clayton Kraatz for First Place. Naeger will be returning to Hollister, California, behind the wheel of the same ’08 Avalanche buggy, albeit with a few mods. This year, there will only be one Champion.

A 350ci GM Ram Jet V-8 sits nestled in the chassis and Naeger estimates its output at 350 horsepower and 400 lb-ft of torque. However, a flick of a switch activates a NOS fogger kit from Redline Performance that offers another 150 horsepower. The engine is fitted with 24-pound injectors (replacing the stock 22-pound injectors) and Hedman headers and it’s cooled by a mid-mounted C&R Racing radiator with a 16-inch-diameter electric fan. Other mods include a Painless Performance wiring harness and a pair of Optima YellowTop batteries. Power is routed through a Transmissions To Go-prepped TH400 transmission with a manual valve body, Stef’s pan, and a Hurst Pistol-Grip shifter. A Sumner Machine Works NP203/205 doubler sends the power to the axles. On the rear of the transfer case is a custom brake rotor with two Wilwood four-piston calipers.

Most memorable moment from 2008: “Tying for First. On the last day I was hoping for Second and had my doubts on that. We had no idea we still had a chance.”
Wants First Place in: “Tank Trap. It was my favorite event.”

“I know I’ll be up against a lot more expensive, lighter, and bigger horsepower rigs, but will try to finish every event as high in the points as we can and maybe the big guys will mess up.”
—Jeremy Naeger

Inside the rig, Naeger monitors underhood activity including engine rpm, voltage, oil pressure, transmission temperature, and fuel pressure, via Auto Meter gauges. Other interior features include a Grant steering wheel and a hydro-steering toggle switch that’s conveniently located on the right side of the steering column.

Mike Karwath, owner of Shotgun Fabworks in Verona, Kentucky, was the top-finishing buggy in 2010 and he did it behind the wheel of his 468ci V-8-powered Jeep YJ buggy. But that’s not what he’ll be driving in TTCC. Karwath will be behind the wheel of Leo Kuether’s incredible Fat Girl buggy, which also competed in 2010 and carried Kuether to a First Place finish in the Frame Twister, Obstacle Course, and Hill Climb.

Most memorable moment from 2010: “A huge highlight of the trip was the time spent with my team and the other competitors around the campfire every night. Knocking back a few cold ones and trading stories from the day’s festivities helped us all relax and prepare for the next day. Hearing your name called as the winner is pretty damn cool as well. Standing on that stage with Brad accepting our award was something I’ll never forget. It’s the high point of my wheeling career.”
Wants First Place in: “Tank Trap, most definitely. It’s worth the most points and often decides the outcome of the entire event. It’s the rockstar event and even if you don’t do well, you’re still in the spotlight. With everyone lining the hillsides watching it’s like you’re in some insane arena battling this ridiculous trail. It throws everything at you in a five minute period: insane water holes, mud, rocks, canyon climbs, etc. You have to be on your “A” game. One simple mistake and you’re on your top.”
Karwath says: “I’ve already used the toenail thing, not thinking that I would ever be asked this again, so this is a tough one. I’m a pretty transparent person. If you’ve met me, you know me. I’ve seen every Broadway musical to hit my area in the last 10 years. Season tickets, bitches! When you’re a Jet you’re a Jet all the way, from your first cigarette to your last dyin’ day.”

“I made a ton of friends the year I was there and still talk to quite a few of them every week. That was the real prize of the trip.”
—Mike Karwath

Outstanding visibility, functionality, and safety are the name of the game for the Fat Girl’s interior. There’s a pair of Kirkey Racing seats, 3-inch-wide racing harnesses, a Grant steering wheel, Auto Meter gauges in a custom center bezel, various easy-to-access toggle switches, rear steer control, and a center-mounted Power Tank.

Some of the engine’s features include an MSD Pro-Billet distributor, Sanderson headers, Dynomax mufflers, and a 3-inch-diameter dual exhaust. A custom 10-gallon fuel cell feeds the engine and an Optima YellowTop battery provides cranking amperage. Keeping the ’plant cool is a custom Forx radiator with two 14-inch-diameter electric fans. Bolted to the engine is a PTC TH400 three-speed automatic transmission with a custom valvebody. It’s cooled by an AFCO extruded cooler and shifted by an Art Carr shifter. An Advance Adapters Atlas 4.3:1 ratio two-speed transfer case sends power to the custom Grand Forks Welding-fabbed driveshafts. The front shaft is made from 2.5-inch-diameter, 0.750-inch-wall material and the rear ’shaft is made from 3-inch-diameter, 0.750-wall material. Both driveshafts use 1410 U-joints.

Clayton Kraatz was an alternate in TTC ’07 but he was voted in as a competitor for TTC ’08 and promptly drove his awesome 467ci V-8-powered ’06 Evolution Warthog to a First Place tie with Jeremy Naeger. Kraatz will compete in TTCC, but here’s a twist, he’ll be driving ’09 TTC competitor Leroy Latham’s awesome rear-engine buggy. Latham took Third Place in 2009 with the rig including a First Place finish in the Obstacle Course.

The interior of the rig is a lesson in simple functionality. It may almost seem sparse, but in fact it has everything Kraatz will need. There’s a pair of RCI seats; a Grant steering wheel; Auto Meter engine temperature, oil pressure, voltage, and tachometer gauges; a “modified crusty old B&M” transmission shifter; and a custom switch panel located on the transmission tunnel. The carpet “matches the drapes.”

Does this TJ look long to you? Well it is, because the wheelbase has been stretched to 101 inches. The rear frame has been notched, plated, boxed, and tied into the rollcage. Fox modified an off-the-shelf front bumper and made the rear bumper as well as the rocker protection. The front bumper holds a Warn M12000 winch with Master Pull 3⁄8-inch Superline. The rear flares are modified Poison Spyder DeFender units and the front fenders are stock Poison Spyder DeFender units. The body sits on a 1-inch lift and the louvered hood is mainly for aesthetics though it does help to provide lower underhood temperatures. TrailReady HD Series beadlock wheels are surrounded by 40-inch Goodyear Wrangler MT/R with Kevlar tires. The rig’s Emerald Green paint was applied by Long’s Auto Body in Bremerton, Washington, and any visible striping was done by “Washington’s finest pine and fir trees.”

Driving: 1997 Jeep Wrangler

Tony Fox was up against some tough competition at TTC ’94 (which incidentally was the first year for the Tow Test), including an M38 and a Scrambler 6x6, but he came out on top in his relatively simple ’79 CJ-5. It was powered by an AMC 304ci V-8 and it rode on Dana 44 axles with a leaf-spring suspension. Oh, and 33-inch tires that are tiny by today’s standards. Fox is returning to Hollister in a Jeep, but this time he’ll be driving his wife’s street-legal TJ. Seriously.

Sounding Off
Most memorable moment from 1994: “Being announced the winner. I thought Kevin with the 6x6 was winning the whole time, so we really didn’t know we were contenders and the judges kept everything hush-hush. Close second was blasting through the Mini-Rubi, because the first eight rigs all got towed out and we just cruised through in a really fast pace.”
Wants First Place in: “Tank Trap, because I think it’s got the most amount of points. But really, I’d be happy to do well in any of the events, considering I’m going to be a runt amongst giants.”
Fox says: “I built this TJ for my wife to drive (I normally drive my YJ), and it will be returned to her for wheeling and snow trips after TTCC. Just add some mud flaps and it’s still street legal. Might be the only street legal rig here. I chose this rig because it was easier to adapt for 40s or 42s than a leaf-sprung rig would have been and still be able to return the rig to our normal wheeling activities when it was over.”

Occupants of the TJ are kept safe by a Bent Metal Customs six-point rollcage and MasterCraft Safety five-point harnesses on the MasterCraft Safety Baja RS seats. If it gets cool in Hollister, Fox can switch on the seat heaters. The gauge cluster looks stock, but it isn’t. It’s a custom setup with recessed Auto Meter gauges displaying engine coolant temperature, oil pressure, fuel level, alternator output, speed, and engine rpm. The dash pod has a gauge showing transmission temperature and it also houses the winch controls, seat heater switches, and miscellaneous lights. Other interior features include a Subaru radio, Cobra CB, a race radio, and a modified Art Carr transmission shifter.

Top Truck shook in 1997, but it wasn’t an earthquake that caused it. It was the shock of Geby Wager’s amazing big-block-powered, M561 Gama Goat-axled, independent suspension-equipped CJ winning TTC. The street-legal rig was built to drive on top of snow 4 to 20 feet deep as well as cross country where there are no roads or trails. It apparently handles Top Truck terrain well, too. Wager will be returning to Hollister in the CJ and even after 15 years the rig is very similar to the way it was in 1997.

Sounding Off
Most memorable moment from 1997: “How supportive the other competitors were.”
Wants First Place in: “The Tank Trap. It is the most diverse and so is our vehicle. It also looks like all the events are geared to 54-inch tires with not much opportunity for smaller vehicles, or team skill, without winching. The Tank Trap allows a bit more time for the winching.”

“We strongly believe that you can’t get somewhere that no one has ever been by following tracks. But that can be scary.”

Inside, occupants sit in Beard seats and Wager grips a steering wheel lifted from a Pontiac Fiero. A full complement of Auto Meter gauges reside in the rig including oil pressure, coolant temperature, voltage, and speedometer. A custom heads-up display by Creative Motor Sports allows Wager to control the air suspension. There are preprogrammed settings, or he can control it with a joystick. This system gives him complete control of the air springs either individually or as a complete unit.

  • Up front is an IFS that uses a combination of military M561 Gama Goat 6x6 parts and custom parts. The center differential is a limited slip-equipped Gama Goat differential while the axleshafts are custom with larger-than-stock U-joints. The Gama Goat steering knuckles have been modified to accept custom spindles with custom stub shafts along with Speedway Engineering Wide 5 hubs. The suspension utilizes air springs and a Fox remote-reservoir shock at each corner. The springs are individually controllable from the cab and the CJ’s tube frame acts as an air tank, fed by an engine-driven modified air conditioning compressor. The setup uses an inboard braking system consisting of 12-inch-diameter Wilwood disc brakes and Wilwood four-piston calipers. The big 46-inch tires are pointed via a crossover steering system that includes a Cadillac steering box and a high-performance pump.

Does this TJ look long to you? Well it is, because the wheelbase has been stretched to 101 inches. The rear frame has been notched, plated, boxed, and tied into the rollcage. Fox modified an off-the-shelf front bumper and made the rear bumper as well as the rocker protection. The front bumper holds a Warn M12000 winch with Master Pull 3⁄8-inch Superline. The rear flares are modified Poison Spyder DeFender units and the front fenders are stock Poison Spyder DeFender units. The body sits on a 1-inch lift and the louvered hood is mainly for aesthetics though it does help to provide lower underhood temperatures. TrailReady HD Series beadlock wheels are surrounded by 40-inch Goodyear Wrangler MT/R with Kevlar tires. The rig’s Emerald Green paint was applied by Long’s Auto Body in Bremerton, Washington, and any visible striping was done by “Washington’s finest pine and fir trees.”

Name: Alex Sanders
Champion in: 2011 (Buggy Class)
Driving: 2008 Homebuilt Buggy

After pulling off an upset win in the 2011 Top Truck Challenge Buggy Class, Alex Sanders has the unheard of opportunity to take the trophy home in consecutive years. Returning with his ’08 home-built buggy, Sanders has a few changes up his sleeve, but overall the buggy will be familiar to those who monitored Top Truck in 2011, following the philosophy of “If it ain’t broke, go win Top Truck again.”

Sounding Off
Most memorable moment from 2011: “All of it! Mainly when I didn’t wheelhop or break in the Tow Test. And partyin’ with and meetin’ so many cool people.”
Wants First Place in: “Mini Rubicon. Because even though I love the Tank Trap the Mini Rubicon seems the most technical.”
Sanders says: I just plan on driving smart and having fun this year.”

“I don’t plan on winning this year with all of the great competitors, but then again I didn’t plan on winning last year either.”
—Alex Sanders

Believe it or not, we’d never had a rule requiring a firewall before and in 2011 Sanders showed up without one. After reexamining our rulebook, we modified the rules requiring all rigs to have a firewall and Sanders complied. Even with the new addition, the cab is as sparse as possible with only two gauges that monitor oil temperature and oil pressure. A www.12voltguy.com winch switch is positioned between the seats and the VW brake and clutch pedals are a nice touch.

  • Unique for its front “grader-ball” suspension, the buggy gets huge flex for little cost, thanks to a triangulated single link. The grader-ball uses a trailer-style ball and mount sourced from a road grader and welded to the frame crossmember. A matching coupler, mounted to the axle via a solid V-link, is welded shut so that it can’t separate from the ball. From there a pair of coil springs control the 2 1/2-ton Rockwell axle and an owner-fabbed panhard bar locates it laterally. Front shocks, fashioned from hydraulic rams, deliver 25 inches of travel.

The 2 1/2-ton Rockwell axle is located by Tuff Country GM truck front leaf springs and damped with long-travel Tuff Country shocks. Just like the front axle, 6.72:1 gearing and welded spiders fill the housing, while power is delivered via “school bus” driveshafts attached to an NP205 transfer case. Stopping power comes courtesy of a pinion brake.

  • Last year Sanders was running a 350ci V-8 bored 0.040-inch over, stretching the displacement out to 358 cubic inches. Sanders’ plan was to run a 400ci V-8 this year, but there was too much skirt clearance, so he bored it 0.030-inches over and used a set of TRW flat-top pistons with 5.7 rods and a custom-ground Comp Cam. Channeling the torque to the dirt is an SM465 four-speed manual transmission.

We last saw Burton in 2006 when he took top honors at TTC in his stretched Jeep Wrangler TJ. Burton’s TJ is notable for its four-door configuration, which Burton began building in 2005, over a year before the four-door Wrangler was offered from the factory. The ’97 TJ body was grafted to the rear tub of a Wrangler YJ, and even includes a trick, narrowed CJ-7 tailgate. Burton mowed down the obstacles once at TTC, will he be able to do it again?

Most memorable moment from 2006: “In the Tank Trap canyon something on the Jeep started smoking real bad and we were not sure what it was. It was so bad I had to shut the engine off to let it clear so we could see. Really was not sure it was going to restart. Luckily once we winched a bit and leveled out the smoke got better and we were able to finish.”
Wants First Place in: “Tank Trap. Double points and what we all came to conquer.”

“I enjoy tinkering with Jeeps, trucks, snowmobiles, ATVs, sand rails, or anything with a throttle. I have to thank my parents for that, as my first trail ride happened when I was just five months old and have been hooked ever since.”
—Brent Burton

With stretched bodywork and seating for five, Burton doesn’t have to choose between his family and his gear on the trail. Overall, the interior retains a stock feel, but factory buckets have given way to MasterCraft Safety racing seats while a www.12voltguy.com winch controller falls at Burton’s fingertips. Auto Meter gauges supplement the stockers for relaying vitals to the driver.

Ellis’ Samurai, with its 37-inch paddles, looks a lot like the little toy 4x4 we all grew up dreaming about driving when we were young. With an 84-inch wheelbase and exceptional approach, breakover, and departure angles, this mini-rig might just be might nimble enough to go around obstacles in a competition, although the rock rash might suggest otherwise. Ellis says he has removed some weight, added a snorkel, and equipped the four-banger with a 175hp shot of nitrous and methanol injection in preparation of Top Truck. A Warn 9.5 winch should have no problem pulling the Sammy out of a jam.

Name: Randy Ellis
Champion in: 1995
Driving: 1986 Suzuki Samurai

Randy Ellis is no stranger to the world of wheeling. The well-traveled Ellis won Top Truck back in 1995, and continues to contribute to our sport today through his company, Randy Ellis Design. When Ellis took home his orginal TTC trophy, it was with an ’80 Jeep CJ-5 powered by a Chevy 377ci V-8 and rolling on 35-inch tires. The Jeep featured a three-link suspension, the first time a multilink setup appeared at Top Truck. For 2012, Ellis is out to prove himself again, this time with a self-built ’86 Suzuki Samurai powered by a Geo Tracker 1.6L four-cylinder riding on huge 16.00-17 (37x16) Revolution paddle tires. We can only imagine that the Tank Trap gods are drooling at this news.

Open the hood and you’ll find a 1.6L four-cylinder engine from a Geo Tracker. The little mill should be good for about 95hp and 98 lb-ft of torque, although that should nearly double for brief periods of time when the plumbed-in nitrous and methanol injection systems are activated. A stock five-speed manual trans transfers power to the ground via a Samurai T-case with 4.16:1 Calmini gearing.

In 2010, we split the classes up between trucks and buggies and Jason Gray walked away with the inagural TTC truck class trophy. Having to grind through mechanical issues with his ’75 GMC pickup in 2010, Gray is coming better prepared and ready for an all-out assault on the Champion’s Challenge. However, the Tank Trap isn’t going to be as easy as it was in 2010 and neither is the competition. Thankfully he has had the helping hands of his 4x4 club, Poorboy Offroad.

The engine has been bored 0.030-inches over and inhales through an Edelbrock Torker manifold, while exhaling through a 2.5-inch stainless dual exhaust and Flowmaster mufflers. A Turbo 400 with a stage II shift kit sends power through the NP203/205 doubler, on down through beefy driveshafts with 1410 U-joints.

  • When Gray competed in 2010, his rig was equipped with a Dana 60 front axle, but not anymore. The latest variation of this GMC comes to the competition sporting a Rockwell 2 1/2-ton axle with 2-inch, Ouverson 47-spline ’shafts, 6.72:1 gears, Ouverson Violator joints and an Ouverson locker. Ruff Stuff Specialty’s brackets and 1 1/4-inch spherical rod ends were used in the reworking of the four-link suspension to accommodate the new axle, while a DIY4X Rockwell skid provides diff protection. Gray is still using the F-O-A coilovers and air bumps from 2010, but has upgraded the steering to a PSC 3-inch double-ended ram system to turn the big Mickeys.

Just as it is in the front, the rear Rockwell has 2-inch shafts, 6.72 gears, and a DIY4X Rockwell skid, although an Ouverson spool is used for locker duties. Gray also swapped out the previous air shocks and is using F-O-A coilovers and air bumps in their place. To help control the rear suspension, a Warn 3.0 ATV winch has also been added and pinion brakes slow the whole thing down on demand.
