Diesel Brothers

Diesel Nation rolls out the red carpet for some of the biggest stars the show has ever seen. From Shaquille O'Neal to Guy Fieri, the guys check out awesome garages and challenge each other to spicy competition.

Nobody's perfect -- not even the Diesel Brothers. Special guests such as Richard Petty and Farmtruck and AZN relive their most embarrassing moments, and Keith Spiker from the Dirty 7 has no idea what kind of redemption battle he's in for.

Heavy D surprises the mechanics with his latest build: a tank. He has big plans for the beast, but must first find a new engine and get it moving again. Meanwhile, Heavy D, Diesel Dave and the Muscle personally trick out their latest giveaway truck.

The Diesel Brothers continue work on their rival builds for the first ever "Tour de Utah" off-road race. Heavy D pulls out all the stops for his AMC Eagle conversion while Diesel Dave and team smash together a Brat and an Impreza to avoid a full build.
