8.8 Solid Axle
editFord first used the 8.8 axle in 1983 model year trucks and is still in production for the Ford Ranger and Ford F-Series. It was also used in the Ford SUVs until Independent suspension replaced the solid axle. Ring, pinion and carrier all remained between the solid axle and independent rear suspension.
The solid rear axle from 1995-2001 Explorers is a popular swap for older Jeep Wranglers and Cherokees. In addition to being nearly the same width, they have the same wheel bolt pattern, are equipped with disc brakes, and are much stronger than the Dana 35 they replace.[1]
It was also used in V8 equipped Mustangs from 1986 to the 2014 model years; and all Mustang models from 2011-2014.
