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
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.

Most memorable moment from 1995: “Being the only one to the top of the Hill Climb.”

“I like beer.”

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.

  • The mostly stock interior is sparse and functional, upgraded with Beard seats for all-day comfort on the trail or 15-minutes in the Tank Trap.

  • The front axle is a Dana 30 out of an ’86 Jeep CJ-7 with Dana 44 outers and RCV axleshafts. Stuffed in the pumpkin is an ARB Air Locker and 5.38 gearing. A simple suspension with modified OME YJ leaf springs and 2.5-inch King reservoir shocks should be both tough and reliable. Steering duty is handled by a PSC hydraulic-assist setup used in conjunction with a crossover system adapted from Tracker parts.

  • Underpinning the rear of the ’Zuk is a custom three-link suspension system using Walker Evans Racing 2.0 air shocks and a panhard rod to locate the Dana 44 axle. Chromoly ’shafts, 5.38 gears, and an ARB Air Locker complete the axle out back.

Gray’s GMC was built with off-road abuse in mind. Featuring a stout foundation, durable components, and a narrowed body designed for extreme clearance and enhanced visibility; trail obstacles don’t easily slow the rattle-canned Pumpkin Orange pickup. Gone are the 46-inch Mickey Thompson tires, in favor of 54-inch Mickey Thomson Baja Claw tires.

Name: Jason Gray
Champion in: 2010 (Truck Class)
Driving: 1975 GMC pickup

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.

Most memorable moment from 2010: “Crossing the finish line in the Tank Trap.”
Wants First Place in: “I would like it to be the Tank Trap. Not only are the points worth more, but it is the grand finale event of the week.”

“I heart ta tas.”
—Jason Gray

From behind the driver’s seat, the view out is pretty good for a fullsize. Drivetrain vitals are monitored by Auto Meter gauges and the driver is supported by comfortable Ford Escort GT seats. A www.12voltguy.com switch panel is located within easy reach on the tubular center console.

  • Providing motivation is a propane-fed GMC 454ci V-8, which is cradled by a 1 3/4-inch DOM cage that doubles as support for the suspension and steering. 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.

  • More changes came in the rear, where the GM 14-bolt axle was also ditched for a Rockwell 2 1/2-ton. 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.
