Season 4

A long-time client wants to improve upon a near-perfect '68 Ford Ranger. The team is up to the task with an all-new custom chassis, handmade interior, rebuilt bed and Coyote 5.0 engine swap. Plus, the guys check off new custom upgrades on a '75 Bronco.

A 1996 Impala throws the guys a curveball when they discover it's an imposter. The team makes it better than ever, with custom body fabrications, rear subframe and handmade interior. Also, Bill gives back a fully-custom 2019 Ram to a Northside neighbor.

Bill's no stranger to truck builds getting bigger than originally planned, so it's no surprise when a 1971 Suburban goes even bigger with a custom lifted air suspension and interior. Plus, a nearly finished 2006 Kodiak needs just one more custom upgrade.

With all its wiring and computerization, not many shops would try to drop a new 2020 Denali dually all the way to the floor. To get it done right, Bill and his team make one of their longest custom chassis ever. Plus, Ekstensive gets a diesel pro-mod drag car back on the track.

Ekstensive turns a stock 2020 Denali dually into frame-dropping, show-stopping work truck. As a final touch, Bill handmakes articulating speakers for the bed. Bill takes a family's minds off their brush with a tornado with a custom 2019 Polaris Ranger.

A '64 Lincoln has been collecting dust for years. Bill and the guys bring this classic back by making it a custom "one weather" roadster with a late-model Coyote engine and handmade interior. Plus, the Sling-Ray is a custom automotive sensation, but Ekstensive has what it's been missing.

A 1971 Suburban returns to the shop for ‘Phase Two,' wanting more power and even more custom metalwork. When a client finds parts and pieces of a ‘68 C10, Bill and the crew set on a new course on a ground-up build unlike any they’ve ever done before.

Bill gets déjà vu on a 1985 Chevy C10 square body. After a long history of building custom C10s, he and the team try to outdo themselves with a handmade chassis and air ride, interior and bed. After a near brush with disaster, Ekstensive makes a 1923 T-Bucket street safe.

A local client wants to surprise his dad with a custom '46 Ford Coupe. Starting with little more than a car skeleton, the team builds it from the ground up. With a history of surprising his wife with custom vehicles, Bill goes classy and supercharged with her 2021 Escalade.

When Ekstensive needs a new shop truck, Bill and the guys go sky-high with a lifted '21 F-450 King Ranch capable of hauling a trailer packed with over 20,000 pounds. With most of the '46 Ford Coupe body beyond repair, the team has no choice but to build from the ground up.

The guys hit the home stretch on the '46 Ford "Blue Thunder." Ekstensive powers up Bill's all-tube buggy with a 1,500 hp Cummins diesel engine, and actor John Cena drops off a '69 MGC, wanting nothing less than to change the game with his British classic.
