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.

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.

  • 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.”

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.
