Bring your 1979-1993 Fox Body Mustang's rear suspension into the modern age with the Detroit Speed Rear Speed Kit, engineered to deliver maximum performance, superior handling, and modern ride quality that far surpasses stock setups for street and track use. This comprehensive kit combines DSE's advanced coilover conversion and Swivel-Link technology to eliminate bind, improve traction, and provide tunable damping, making it an essential upgrade for enthusiasts demanding performance excellence without complex modifications.
Bolt-On Coilover Conversion: This rear coilover conversion kit repositions your rear springs and shocks to the frame rail for enhanced strength, maximum wheel and tire clearance, and compatibility with future mini-tub installations, allowing your Fox Body to handle wider tires and aggressive setups while maintaining a clean, bolt-on installation that outperforms factory torsion bar or leaf spring systems.
"Detroit Tuned" Shocks: This kit features DSE's "Detroit Tuned" valved non-adjustable JRi shocks, offering exceptional street ride quality and track performance, enabling drivers to achieve balanced handling that stock shocks simply can't match.
Swivel-Link Technology: Detroit Speed's Swivel-Link technology replaces your factory control arms with stronger, bind-free links that allow full suspension articulation without noisy spherical rod ends, providing easy on-car adjustments for wheelbase and pinion angle to boost traction, reduce driveline vibrations, and deliver smoother power delivery during acceleration and cornering.
Increased Clearance: Designed with laser-cut brackets that accommodate up to 3" custom exhaust systems (with potential minor fuel tank mods depending on setup), the kit ensures compatibility with stock axles and frames, offering versatility for builds focused on performance without sacrificing exhaust routing or overall vehicle integration.
Reduced Body Roll: Included is also DSE's tubular 3/4" rear swaybar for superior cornering control and stability. This sway bar utilizes an upgraded mounting method by attaching to the rear end housing and frame rail; much stronger than your factory mounting locations. Low-friction ball-style endlinks, bushings, and other hardware are also included.
Maximum Traction and Axle Control: The Rear Speed Kit 3 adds DSE's Adjustable Track Bar kit, designed to keep your rear axle centered in all situations. In hard cornering, acceleration, and braking, the rear axle is prone to shift side to side, hindering traction and off-the-line acceleration. The Adjustable Track Bar mounts to the rear chassis of your Mustang, keeping your axle exactly where it needs to be for predictability and stability.
