Detroit Speed Coilover Front Conversion Kit - Single Adjustable Shocks - BBC (1968-1972 GM A-Body) - 030309-SDS
Bring modern coilover performance and adjustable suspension control to your big-block GM A-Body with the Detroit Speed 030309-SDS Front Coilover Conversion Kit. Engineered for 1968-1972 GM A-Body applications with Big Block Chevrolet engines, this direct bolt-in system upgrades the front suspension with modern coilover spring and shock technology. Detroit Tuned valving, extensive ride-height adjustability, and driver-adjustable rebound give you greater control over both stance and suspension response while maintaining excellent ride quality on the street.
The 030309-SDS features single adjustable aluminum-body coilover shocks with Detroit Tuned valving. Building on the features of Detroit Speed's base shock, the single adjustable version adds rebound adjustment with the simple turn of a knob. This gives you the ability to fine-tune shock response for the vehicle, driving conditions, and performance goals without the additional adjustments of a double adjustable shock.
Detroit Speed pairs the shocks with 650 pounds/inch coilover springs with a 9.5 inch free length for the Big Block Chevrolet application. The coilover configuration provides extensive ride-height adjustability, allowing you to dial in the front stance while maintaining an integrated spring and shock package. The included thrust bearings and thrust washers help make spring adjustments easier, while the supplied Detroit Speed spanner tool gives you the proper tool for making coilover adjustments.
The 030309-SDS is engineered as a direct bolt-in front coilover conversion and includes the necessary components for installation. The package includes two Detroit Speed Tuned coilover shocks, two coilover springs, spring adjusting nuts, flat washers, rubber insulators, thrust bearings, thrust washers, mounting hardware, a Detroit Speed spanner tool, and installation instructions. Rather than piecing together unrelated suspension components, you get a complete system engineered specifically for the 1968-1972 GM A-Body platform.
For a big-block Chevelle, GTO, Skylark, Cutlass, El Camino, Monte Carlo, or other compatible GM A-Body that needs more tuning capability than a fixed-valving shock without stepping up to a double adjustable setup, the Detroit Speed 030309-SDS offers an excellent balance. Its BBC-specific 650 pounds/inch springs, adjustable ride height, Detroit Tuned valving, and easy rebound adjustment make it a strong choice for street performance, restomod, and Pro-Touring builds.
