This 1984 Jeep Wagoneer originally came with a 4.2 L inline-six and T-5 five-speed manual transmission. The SUV visited The Jeep Farm in Arizona for a power plant change. While there the company swapped a 5.3 L Vortec V8 and NV3550 five-speed manual transmission. From there torque is transferred to a Dana 44 front axle and AMC 20 rear axle. The Jeep Farm also installed a Deaver 2-inch suspension lift with their reverse shackles. Behind the restored wheels with 31-inch tires are disc brakes in front and back.

This jeep came with a 4.0 in 1984, only 2 years before the 4.0 was released for sale!
Thanks for catching that. We updated the article.
