A heavily braced Chrisman housing is filled with monster-size gun-drilled axleshafts that turn the drive plates of the full-floating rear axle assembly. The overkill axle strength is called on regularly when the truck lands with all its weight on one of the rear corners. A 10-1/2-inch Precision ring gear is bolted to a full spool that permanently locks both wheels together for maximum traction on the slippery Midwestern courses. The Precision Gear ratio is 6.20:1. Rear suspension travel is held at the CORR-mandated limit of 20 inches.
