RideTech 1979-93 Mustang Independent Rear Suspension Systems

Transform your Fox Body's handling with a RideTech 1979-93 Mustang Independent Rear Suspension System. It's no secret that independent rear suspensions (IRS) are superior in almost every way over a stick axle. The biggest concerns are cost and ease of installation. This independent rear suspension system replaces the stock live design with tubular upper and lower control arms utilizing custom-made spindles with S550 Mustang hubs. Camber, roll center, and toe angles were also optimized for greatly increased handling. The bolt-in design requires no welding for installation, as the IRS cradle is designed to mount to the rear frame rails and modified factory mounting points. If you want to optimize the rear suspension of your Fox Body Mustang, do it with this highly engineered IRS system so you can hit the track or street with confidence.
