Longtime desert racer Kreg Donahoe isn't slowing down by visiting Moab, he's expanding his horizons. The dynamics of high-speed vehicle control provide a smooth segue into the world of Low range and lockers. "The purpose of suspension is to not upset the vehicle," Kreg advises. "That's true whether you're going fast or slow." Team Donahoe used Moab as a test bed for its new JK Wrangler suspension. Off-Road's Smurf-blue FJ Cruiser joined the Donahoe JK Wrangler and the Donahoe Class 3 FJ Cruiser for a shakedown run on Hell's Revenge. Kreg's four-door JK runs on 37-inch Nitto Mud Grapplers mounted to KMC beadlock wheels.
