DSE QuadraLink Rear Suspension Kit - Non-Adjustable Shocks (041714DS) - 1970 - 1981 Pontiac Firebird
Bring modern rear suspension performance to 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 its patented Swivel-Link technology for improved handling, precise rear axle control, excellent ride quality, and smooth suspension articulation. The Swivel-Link design allows the suspension to pivot without binding, while tuned high-durometer rubber bushings eliminate the noise, wear, and compromised street manners associated with heim joints.
The 041714DS configuration includes DSE/JRi aluminum-body non-adjustable coilover shocks with Detroit Tuned valving, giving your second-generation Firebird performance-focused damping without the need for external shock adjustments. Long upper links provide excellent pinion and U-joint angle control, while improved anti-squat geometry helps keep the rear suspension composed under acceleration. A long adjustable Panhard rod precisely locates the rear axle laterally during hard cornering and allows roll center adjustment as ride height changes. The rear upper shock crossmember strengthens the rear body and frame section, while inboard-offset lower links provide additional tire clearance for performance-oriented wheel and tire combinations.
