DSE Rear Speed Kit 3 - Single Adjustable Shocks (041647-SDS) - 1979-1993 Ford Mustang / 1979-1986 Mercury Capri
Take control of the Fox Body rear suspension with the Detroit Speed Rear Speed Kit 3. Designed for 1979-1993 Ford Mustang and 1979-1986 Mercury Capri applications, 041647-SDS addresses key limitations of the factory suspension while improving geometry, traction, stability, ride quality, and overall driving confidence. The system combines Detroit Speed's Rear Coilover Conversion, Swivel-Link rear suspension, tubular rear sway bar, and Adjustable Track Bar into a comprehensive package built for everything from daily driving and spirited street use to the dragstrip, autocross, and track.
The single adjustable shocks feature Detroit Tuned valving with convenient rebound adjustment using a simple knob, giving you meaningful suspension tuning while maintaining excellent street ride quality. Swivel-Links eliminate suspension bind and allow full articulation without noisy spherical rod ends, while the 3/4-inch tubular sway bar provides effective chassis-to-axle roll control. The Adjustable Track Bar adds the lateral axle control missing from the factory Fox Body four-link, helping keep the rear axle centered throughout suspension travel and locating the rear roll center 1-1/2 inches below the axle centerline.

Fitment Notes
Detroit Speed 041647-SDS is designed for compatible Fox Body applications using the stock axle configuration. The Adjustable Track Bar brackets attach using holes added to the frame rail and U-bolts at the factory 8.8-inch rear axle. The coilover conversion is required before installing the Swivel-Links because the links do not incorporate factory-style spring perches. Custom exhaust clearance up to 3 inches depends on tire and mini-tub width, and fuel tank modification may be required with some combinations.
