    Features:

    • Ideal for daily driving and light-duty hauling
    • The axle brackets are compatible with the original axle, wiring, and brake lines
    • The Swivel-Links allow pinion angle and/or wheelbase to be adjusted without completely unbolting the link
    • The double-adjustable shocks have remote canisters with a gas-charged bladder to provide high-frequency and low-speed dampening control
    • Upper shock mounts are adjustable by 1 in. (up or down) allowing ride height changes without affecting shock travel
    • C-Notch plates gain additional axle clearance at lower ride heights
    • Tuned high-durometer rubber bushings provide smooth, silent-motion articulation
    • The horizontal trackbar delivers effective rear axle lateral location during hard cornering and is adjustable to correct roll center control at different ride heights
    • High-strength steel crossmembers add rigidity to the rear body and frame section
    • Weld-on installation delivers a permanent and stronger 4-link system
    • Bring Modern-Day Rear Suspension to Your Classic Hot Rod

      Detroit Speed QuadraLink Rear Suspension Kits are a great way to upgrade from an original leaf spring suspension configuration. Unlike competitors, DSE’s exclusive 4-link geometry design is uncompromised to achieve the best possible handling. A QUADRALink rear suspension provides a performance increase in an easy all-in-one package. They feature high-durometer rubber bushings for smooth articulating, greater pinion, and u-joint angle control and utilize a Panhard rod that provides precise and effective rear axle lateral location.
