Who doesn’t love a pickup truck that can throw diesel plumes like crazy? The Diesel 4×4 (D4x4) is one of the fastest growing classes. Fans will shout their loyalty to their brand of choice as these 8,000 lb pickups come out to shows in high quantities. Running a stock body and an OEM CHassis makes this class the easiest to relate to their farm and work vehicles sitting in the parking lot.
