    QA1's bolt-in rear coil-over conversion kit upgrades the rear suspension of 1979-2004 Ford Mustangs. The kit includes specially designed mounting brackets, single-adjustable aluminum coil-over shocks, springs, and the necessary hardware.

The kit bolts in and is backed by QA1's lifetime shock warranty. It does not fit Cobra IRS models.
