Detroit Speed Coilover Front Conversion Kit - Double Adjustable Shocks - BBC (1964-1967 GM A-Body) - 030307-DDS
Bring modern coilover performance and serious suspension tuning capability to your big-block GM A-Body with the Detroit Speed 030307-DDS Front Coilover Conversion Kit. Engineered specifically for 1964-1967 GM A-Body applications with Big Block Chevrolet engines, this direct bolt-in system replaces the conventional front spring and shock arrangement with an integrated coilover package. Extensive ride-height adjustability, Detroit Tuned valving, and double adjustable shocks give performance-minded builders the control needed to dial in both stance and suspension response.
The 030307-DDS features double adjustable aluminum-body coilover shocks with two independent adjustments and an extensive tuning range. This added adjustability allows the suspension to be tailored more precisely to vehicle setup, driver preference, and performance demands while still providing excellent ride quality on the street. For enthusiasts who want more tuning capability than a base or single adjustable shock can provide, the double adjustable configuration delivers the flexibility required for serious street, autocross, road course, and Pro-Touring builds.
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 higher spring rate is matched to the BBC version of the conversion kit, while the threaded coilover design provides extensive ride-height adjustment. Included thrust bearings and thrust washers help make spring adjustments easier, and Detroit Speed supplies its dedicated spanner tool for convenient coilover adjustment.
The 030307-DDS is engineered as a direct bolt-in front coilover conversion and includes the necessary components for installation. The package includes two Detroit Tuned coilover shocks, two 650 pounds/inch coilover springs, spring adjusting nuts, polyurethane upper and lower shock bushings, aluminum spacers, thrust bearings, thrust washers, mounting hardware, and a Detroit Speed spanner tool. Instead of trying to match individual shocks, springs, and mounting components, you get a complete system engineered to work together on the 1964-1967 GM A-Body platform.
For a big-block Chevelle, GTO, Skylark, Cutlass, or other compatible A-Body that needs modern suspension control without sacrificing street manners, the Detroit Speed 030307-DDS delivers a potent combination. Its BBC-specific 650 pounds/inch springs, extensive ride-height adjustment, Detroit Tuned valving, and double adjustable shocks provide the foundation to fine-tune your classic for the way you actually drive it.
