1997 Jeep Wrangler TJ: Building An

In last month's issue, we began documenting the construction of Off Road Evolution's "Everyman" EVO TJ Wrangler—a crossover trail rig/race rig that would compete in the 2013 Ultra4 King of the Hammers Everyman Challenge. The Off Road Evolution team was working around the clock to complete not only the EVO TJ but also to ready its EVO 1 JK Unlimited, which was taking part in the King of the Hammers' main event. Campaigning one race rig is a lot of work in itself. Campaigning two … well, that's just crazy talk.

Enjoy the following pics and captions of the latest work completed on EVO TJ. We'll feature the finished product in the October 2013 issue.

1. With the deadline looming ever closer, the Off Road Evolution racing team continued its forward push to complete its EVO TJ project, which would compete in the 2013 Ultra4 King of the Hammers Everyman Challenge. 1.

2. A Dynatrac ProRock 60 rear axle was hung from the frame using EVO Mfg.’s new long-arm TJ system. The control arms and track bar are made from 2-inch by 0.500-inch-wall DOM tubing and use 1 1/4-inch Genuine Johnny Joints. 2.

3. The EVO TJ suspension uses heavy-duty bracketry throughout the system that was further fortified with gussets wherever deemed necessary. Additionally, frame-strengthening plates were welded in place in known weak spots along the frame. 3.

5. The ProRock 44 uses Dynatrac ProRock 60 outers, 5.38 gears, and an ARB Air Locker. The track bar, tie rod, and PSC Motorsports hydraulic steering ram will all be protected behind the massive skidplate. 5.

9. After a few mockups, the steering column was placed below the dash bar with support tubes leading down to it. Borgeson steering linkage was used all the way to the steering box. An Art Carr transmission shifter was mounted to down tubes that lead from the dash bar to a crossbar for the seat mounts. The Painless Performance ignition box was installed next to the shifter in easy reach of the driver. 9.

10. The 14-inch-travel King 2.5-inch adjustable compression reservoir shocks were mounted high up on the rollcage C-pillar down tube that leads to the frame and didn’t require any frame notching for clearance. An eight-lug wheel bolt pattern is used for greater strength but also because the EVO team campaigns its eight-lug–equipped EVO1 JK in the King of the Hammers’ main event, so being consistent means the team can swap spares as needed as the wheel bolt pattern, offset, and diameter are the same. 10.

14. The 12-inch-travel King 2.5-inch adjustable compression reservoir shock in coil arrangement was mocked up in the shock towers before final welding. This is not a coilover shock but rather an adjustable shock in a mono-coil setup. The coil doesn’t attach to the shock and both the coil and shock are attached to the frame and axle. A similar setup was used in Dodge trucks in the 1990s and therefore met the Everyman Challenge spec class requirement of utilizing a suspension used in a production vehicle. Also check out how the EVO front bumper protects the PSC Motorsports steering box, which was cycled above the framerail and factory front crossmember. 14.
