This 1981 Jeep Scrambler is an LS-swapped build completed by 1 Off Garage and paired with a Tremec 5-speed manual for an engaging, driver-focused experience. The powertrain is fully built and runs strong; however, this Scrambler would benefit from additional fine-tuning in the steering and suspension to be fully dialed in.

There is some play in the steering felt through the gears at lower speeds, though once cruising in higher gear the Jeep tracks straight. Cosmetic imperfections are present, including rust on the front passenger-side fender and normal undercarriage surface rust consistent with age and use.

With major mechanical upgrades already completed, this Jeep presents an opportunity for the buyer to finish refining the chassis while enjoying the performance of a properly built LS-powered Scrambler.
