Fitment Notice

Fits ALL Mustangs equipped with an 86-93 8.8" rear end.
Although we have seen other wheels not listed above modified to fit this kit, we cannot guarantee correct fitment outside this list.
Some Mustangs may require front fender/fender-well modifications depending on tire size and ride height, especially 1987-90 because of the smaller wheel opening. 1991-93 Mustang has a larger fender opening but still may require modification. Modifications typically include trimming the fender and lower front spat for tire clearance and/or trimming the wheel well liner.
1979-86 Mustangs and 1987-93 2.3L Mustangs need to use 1987-93 5.0L spindles, struts, and calipers for this kit to work.
From the factory, your car came with a 28-spline differential. Upgrading to a 31-spline differential is required for this kit!
