1996 GMC Jimmy With Coilovers, 37s, and 1-ton Axles, Crushing It at KOH 2020

Sam Fabian’s Jimmy is purpose built for trail domination.

We could tell from the 1996 GMC Jimmy's sheetmetal that Sam Fabian of Pennington, New Jersey, wheeled his machine—hard. We caught up with Sam on the lakebed at King of the Hammers 2020 (KOH2020) where he gave us the rundown on what makes his Jimmy work.

Sam's 1996 GMC Jimmy was passed around his family a few times before it found its way to him. He left the 4.3L engine and transmission largely alone while he focused his efforts on nearly every other aspect of the truck.

He bolted a passenger-drop NP241 transfer case to the Jimmy's 4L60E. The 1996 Jimmy's 37-inch Pit Bull Rockers handle relations with the earth below while 2.5-inch Fox coilovers and 2.5-inch Fox bypass shocks soak up the bumpy stuff. A hydraulic ram helps the steering box aim the big meats through the trails while Sam's custom metalwork keeps the frontend—and its winch—protected from damage.

Sam's Dana 60 frontend has 5.38 gears and a Spartan locker while the 14-bolt rearend gets added traction from Lincoln Electric's finest welded spider gears. Barnes 4WD is where Sam got the links for the Jimmy's four-link suspension. The back half of the Jimmy once looked like it did from the factory but now has been opened up to hold the rig's fullsize spare tire.
