Detroit Speed Coilover Front Conversion Kit - Single Adjustable Shocks - SBC / LS (1968-1972 GM A-Body) - 030308-SDS
Bring modern coilover performance and adjustable suspension control to your classic GM A-Body with the Detroit Speed 030308-SDS Front Coilover Conversion Kit. Engineered for 1968-1972 GM A-Body applications with Small Block Chevrolet or LS 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 030308-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 that can be changed with the simple turn of a knob. This lets you fine-tune shock response to suit the vehicle, road conditions, and driving style without the additional complexity of a double adjustable shock.
Detroit Speed pairs the shocks with 550 pounds/inch coilover springs with a 9.5 inch free length for SBC and LS applications. The threaded coilover design provides extensive ride-height adjustability, allowing you to dial in the front stance while maintaining a matched shock and spring combination. Thrust bearings and thrust washers are included to assist with spring adjustment, and the supplied Detroit Speed spanner tool makes it easier to perform coilover adjustments.
The 030308-SDS is engineered as a direct bolt-in conversion and includes the necessary components for installation. The kit includes two Detroit Speed Tuned coilover shocks, two coilover springs, spring adjusting nuts, flat washers, rubber insulators, thrust bearings, thrust washers, mounting hardware, and the Detroit Speed spanner tool. The result is an integrated front suspension package designed specifically for the 1968-1972 GM A-Body rather than a collection of unrelated shocks, springs, and installation components.
For a 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 030308-SDS offers an excellent balance. Its 550 pounds/inch springs, adjustable ride height, Detroit Tuned valving, and convenient rebound adjustment make it a strong choice for street performance, restomod, and Pro-Touring builds.
