Moab regular Dave Cowley knows the Rockpile and, after feeling it out a few times, drove it like he owned it. Dave generally makes more modified rigs look silly by using experience and driving skill with some nice but not extravagant equipment on his '88 K5. The most obvious mod is the bobbed rearend and fender trimming to fit the 39.5-inch Swampers, but the drivetrain is once again where it's at. The almost standard GMD60F/14FF axles run a Powerlok/Detroit combo and are pushed by the nothing-special 350/TH350/NP208. Suspension is a 4-inch Tuff Country front and ORD Shackle flip rear with crossover steering.
