This is a great way to upgrade from original leaf spring suspension. Unlike our competitors, our exclusive 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 with no binding. The best feature is that this is achieved without heim-joints. Heim-joints are noisy and wear out fast.

The Detroit Speed, Inc. 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.

Also included is a rear sway bar. The sway bar is powdercoated gloss black and includes end links, bushings, and mounting brackets for installation. Dont settle for anything less than Detroit Speeds Quadralink rear suspension!
