Heavy D, Diesel Dave, and the Dieselsellerz crew work to reinvent the bullpen car for MLB Network, while working on their biggest commission ever- a Chevy Duramax for baseball legend Miguel Cabrera.

The pressure's on when Detroit Tiger and baseball superstar Miguel Cabrera taps them to build a tricked-out Chevy Duramax for his charity. And the guys try to knock it out of the park with National League themed UTV bullpen car for MLB Network.

The Muscle and Diesel Dave rewrite Heavy D's autobiography, Heavy D takes the Megaram out on a rescue and ends up stuck in the mud, and Heavy D and Diesel Dave need Redbeard's help when their latest build breaks down in the middle of Salt Lake City.

Heavy D and Diesel Dave source a 1984 AMC Eagle they want to turn into their next big, diesel-powered build.

Extreme weather puts the Brodozer's jump over a flying airplane in jeopardy, as Heavy D and the other stuntmen must make their death-defying World Record attempts without practice, on Live TV, in the worst conditions the area has seen in decades.

Heavy D sends Diesel Dave and The Muscle on a secret late-night mission to the spooky overflow lot. However, completing their task becomes difficult when they remember all the builds they've done throughout the years.
