2011 Top Truck Challenge

Brooke Spencer/ Ron Adams: 2009 Custom FJ40 Buggy

Top Truck Challenge 2011 Competitors: Show & Tell

By: Douglas McColloch, Ken Brubaker, Photography by Ken Brubaker, Sean P. Holman
Resting on a “Spinney custom-built chassis” and sporting “Rotting Carcass Green” paint, the FJ40-bodied buggy rolls on 20-inch Stazworks rims shod with 54-inch Mickey TTC Claws. A trusty old Warn 8274 stands at the ready for extraction, and TJM driving lights provide added illumination for night-wheeling runs.

Buggy class:No Small Potatoes
Toyota-themed vehicles don’t often get picked for Top Truck, but Brooke Spencer’s FJ40-bodied buggy is the exception to the rule. With big power, mad-low gearing, and max suspension travel all baked into the mechanical mix, this Idaho-based buggy, piloted by Ron Adams and co-driven by Ben Spinney, aims to be the first-ever Toyota-inspired competitor to take top honors at TTC.

The front suspension is textbook buggy-building, with a double-triangulated four-link and 18-inch-travel RaceRunner 2.5 coilover shocks providing articulation. The pinion-braked Rockwell 2½-ton axle houses RCV 300M axleshafts and 6.72:1 gears, and it gets a steering assist courtesy of a PSC 2.5 ram and pump. We’re kinda digging the cow-catcher-style diff guard/attachment point, too.

  • Most looking forward to:“The Mini Rubicon. I really like rocks.”
  • Not looking forward to:“Mud Pit. Not looking forward to cleaning!”
  • Playing on his iPod/CD player:“Black Label Society.”

  • Inside the FJ, Corbeau buckets keep driver and co-driver comfortable while a Grant wheel turns the Claws. A host of Auto Meter gauges keep an eye on pressures and temps; a 12voltguy panel houses the winch switch; and a Hurst quarter-stick shifter engages the mega-built TH350 sporting six-pinion planetaries, machined pistons, extra clutches and “two big coolers.”

  • Out back, a 2½-ton Rockwell (front) axle gets the full hydro-steer treatment, receives its power from a 32-spline NP205/Klune-V combo, and is located by the same four-link/18-inch-travel coilover arrangement as in the front. Like the front, it too is stuffed with 6.72:1s and 300M shafts. A custom pinion brake aids with stoppage, and a smart-looking skid protects the rear sway bar.

  • Mo’ power from Mopar: 440 beautiful propane-fed cubes of it, to be precise. The block was balanced and blueprinted, and houses milled and polished 426 (real Hemi) heads, which, along with the Edelbrock Performer RPM intake and dual 2½-inch exhaust, help the V-8 crank out an estimated 400 horsepower at 5,000 rpm. An Optima YellowTop cranks it to life, and an MSD Pro-Billet distributor and Blaster coil regulate the juice.
