DSE QuadraLink Rear Suspension Kit - No Axle Brackets - Single-Adjustable Shocks (041715-SDS) - 1970 - 1981 Pontiac Firebird
Replace the original leaf spring suspension on your 1970-1981 Pontiac Firebird with the Detroit Speed QUADRALink Rear Suspension Kit and give your second-generation F-Body modern rear suspension control without sacrificing street manners. Detroit Speed's exclusive 4-link geometry is engineered for responsive handling and excellent ride quality, while patented Swivel-Link technology allows the suspension to articulate smoothly without binding. Tuned high-durometer rubber bushings eliminate the need for heim joints, providing quiet, controlled operation without the noise and wear commonly associated with rod ends.
The 041715-SDS configuration adds DSE/JRi aluminum-body single-adjustable coilover shocks with Detroit Tuned valving and an installed rebound adjustment knob. This gives you the ability to fine-tune shock response while retaining excellent street ride quality. Long upper suspension links provide excellent pinion and U-joint angle control, improved anti-squat geometry helps control rear suspension movement under acceleration, and a long adjustable Panhard rod precisely locates the rear axle laterally during hard cornering. This version is supplied without axle brackets and is intended for builds using a complete rear-end assembly with the appropriate QUADRALink mounting provisions.
