Detroit Speed QUADRALink rear suspension kits offer 4-link geometry for the best possible handling. These kits are a great way to upgrade from your original leaf spring suspension. They feature Detroit Speed's patented Swivel-Link that allows the suspension to fully articulate with smooth, solid motion and no binding—and it's done without Heim joints! QUADRALink uses tuned high-Durometer rubber bushings, rather than noisy, short-life Heim joints or squeaky urethane bushings. Plus, unlike other kits, these suspensions utilize an adjustable panhard rod that provides precise and effective rear axle lateral location during hard cornering. The long upper links provide great pinion and U-joint angle control, while the rear upper shock crossmember strengthens the rear body and frame section. QUADRALink rear suspension kits are available for a variety of specific vehicle applications; select the model to enhance your ride!

By using the chassis to stabilize the rear axle as opposed to the opposing link, the deflection of the vehicle under heavy cornering is minimized. Detroit Speed sway bars mount with a low-friction ball-style end-link, allowing free articulation of the bar, eliminating binding through the range of rear suspension travel.

Detroit Speed adjustable track bar kit adds a critical link to keep the rear axle stable during hard cornering. The factory 4-link is completely ineffective at locating the axle side-to-side as the suspension arms travel vertically, and the addition of a DSE track bar will prevent the axle from wandering unpredictably. The track bar connects to the rear axle to the chassis of the vehicle, which helps keep the axle centered under the chassis during suspension travel. This gives the driver better grip and acceleration off the line and more confidence in the corners. The track bar brackets bolt-on through holes added into the frame rail and U-bolts to the factory 8.8 rear axle.
