DSE QuadraLink Rear Suspension Kit - No Axle Brackets - Double-Adjustable Shocks (041715-DDS) - 1970 - 1981 Pontiac Firebird
Transform the rear suspension of your 1970-1981 Pontiac Firebird with the Detroit Speed QUADRALink Rear Suspension Kit. Designed to replace the original leaf spring suspension, the QUADRALink combines Detroit Speed's exclusive 4-link geometry with patented Swivel-Link technology to deliver modern handling, precise rear axle control, excellent ride quality, and smooth suspension articulation. Tuned high-durometer rubber bushings allow quiet, controlled movement without the binding, noise, and wear associated with heim joints, making this system equally at home on a serious street car or performance-focused pro-touring build.
The 041715-DDS configuration pairs the QUADRALink with DSE/JRi aluminum-body double-adjustable coilover shocks featuring Detroit Tuned valving. Two independent shock adjustments provide a broad tuning range for dialing in suspension response to suit the vehicle, driver, and intended use. Long suspension links provide excellent pinion and U-joint angle control, while improved anti-squat geometry helps control rear suspension movement under acceleration. A long horizontal track bar precisely locates the rear axle laterally during hard cornering and is adjustable for roll center control at different ride heights. This version is supplied without axle brackets and is intended for builds using a complete rear-end assembly with the appropriate QUADRALink mounting provisions.
