QL SUS KIT 70-81FIRE NON-ADJ SHOCKS;If you plan to order a complete rear-end assembly, please order your QUADRALink Kit without axle brackets. Axle brackets require a 3" axle tube.;Detroit Speed QuadraLink Rear Suspension Kit - Base Shocks;1970-1981 Pontiac Firebird;This is a great way to upgrade from original leaf spring suspension. Unlike our competitors, Detroit Speed's exclusive new 4-link geometry design is uncompromised to achieve the best possible handling. The Detroit Speed "Swivel-Link™" (Patent No. 7,398,984) allows the suspension to fully articulate with smooth solid motion an no binding. The best feature is that this is achieved without heim-joints. Heim-joints are noisy and prone to short-term life. The Detroit Speed QUADRALink utilizes tuned high-durometer rubber bushings (in place of heim joints or squeaky urethane bushings). The long upper links provide great pinion and u-joint angle control. Contrary to competitors' kits, our kit utilizes a panhard rod that provides precise and effective rear axle lateral location during hard cornering. The panhard rod is adjustable as ride height changes for roll center control. The rear upper shock crossmember strengthens the rear body and frame section. Don't settle for anything less than our QUADRALink rear suspension!Spring Rate: 250lbs/inSpring Free Length: 8in;No compromises in suspension geometry;Designed to work with Detroit Speed Mini-Tubs or stock tubs (please specify);Great ride;Detroit Speed exclusive no-bind "Swivel-Link™" (Patented) technology;With the Swivel-Links™ pinion angle and/or wheelbase can be adjusted without unbolting the link from the car;High durometer rubber bushings, no heim joints to wear out and make noise;Long upper arms for pinion angle control;Improved anti-squat geometry;Long panhard rod for rear axle lateral control during hard cornering;Stock back seat can still be used;DSE/JRi aluminum body coilover shocks with 'Detroit Tuned' valving;Coilover Springs;Lower links are offset inboard for additional tire clearance;Spanner Tool for easy shock adjustments;All links are powdercoated black
