Diesel Brothers - Season 8

The Diesel Brothers prepare to make diesel history. The Plan? Gather 10 of the most iconic diesel vehicles ever built, give 'em a complete overhaul and auction them off in the baddest diesel auction ever. What could possibly go wrong?

Heavy D thinks he's found gold in a rare Diesel Cadillac, but will it turn enough heads on the auction block to cash in? Diesel Bi-Wheel is almost ready to roll but the guys may need to pump the brakes.

Heavy D enlists a unique semi-amphibious off-road military vehicle that gives Redbeard a sinking feeling. Meanwhile, time's up for the Diesel Bi-Wheel, and they're left questioning its big debut.

Redbeard goes rogue taking on an iconic diesel vehicle build of his own. Will his Hail Mary cost them a Queen's Ransom? Meanwhile it's time to see if the Gama Goat will sink or swim -- literally.

Heavy D rolls the dice on a vintage 1951 International Diesel dozer with engine problems. Is he pushing his luck? Meanwhile, Redbeard announces their first-ever double giveaway to keep some cash flowing into the shop.

The guys get fired up about an overlanding rig, but it turns into a totaled smoke show. Can Heavy D save the day or is the auction going up in flames?

Heavy D bets the farm on a Diesel-swapped Chevy 210, but this rusty Rat Rod could run them off the road. Meanwhile, they're giving away a monstrous new TRX.

Work continues on the Diesel rat rod, but Heavy D's latest military build hits a snag. Will the big rig be battle ready in time for the auction?

Heavy D takes a chance on a unique double Corvette while Muscle takes the lead on a Denali for their latest giveaway. Can they finish before the Diesel auction?

Auction day is finally here and the guys are selling 16 unbelievable builds in the biggest gamble of their careers. Will they crush their sales goals and declare the auction a smashing success? Or will they lose all their money, along with their reputations?
