The rear suspension features a long-travel custom Deaver spring pack along with 10-inch-stroke King 2.5-inch two-tube bypass shocks that deliver 16 inches of wheel travel that help the rear keep up with the front through the rollers. A pair of Synergy limiting straps keeps the shocks from pulling apart when catching major air off a razorback. There’s nothing more fun than blasting up a dune face with gobs of horsepower and paddle tires! The Duramax prerunner has 39-inch BFGoodrich Baja T/A race tires at all four corners, but the paddle tires come out to play when Austin hits the dunes. Here you can see the two spare 39-inch BFGoodrich Baja T/A race tires strapped to the rear of the bed to help keep the truck level while sailing off the lip of a jump.
