Diesel Brothers

The Diesel Brothers are back! Diesel Dave picks his first giveaway truck and dreams big attempting to build the 2020 version of the Kodiak. Todd LeDuc challenges the guys to a desert race and flips the script by picking The Muscle to be on his team.

Diesel Dave continues work on his epic modern-day Kodiak while making sure he doesn't break the bank. Sam the Mad Scientist then unveils "The Kraken" -- a diesel-powered monowheel vehicle that is unlike anything the guys have ever seen.

Mad Scientist Sam's wild creation, The Kraken, comes to life but Heavy D continues to be skeptical of the build's potential viral success. A high profile client wants to customize a Ram 3500, which puts Diesel Dave and The Muscle to the test.

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 tank build, but engine and transmission troubles put the project in jeopardy. Meanwhile, the shop splits into teams for an epic build-off between an AMC Eagle and a Subaru Brat for the Tour de Utah off-road race.

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.

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 wildest 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 success? Or will they lose all their money along with their reputations?
