Independent Rear Suspension System | 1979-1993 Mustang

Revolutionize your Fox Body Mustang with our bolt-in IRS conversion. Independent rear suspension (IRS) is widely recognized as superior to the traditional solid axle setup. Our system overcomes the common challenges of cost and complexity, offering a high-performance, durable solution that utilizes proven components from the 2015-2023 Mustang.

For the ultimate handling package, pair our IRS with our cutting-edge SLA front suspension. This combination replaces your car’s outdated suspension components with a modern double wishbone design, dramatically improving grip and responsiveness.
