Detroit Speed Coilover Conversion Kit - Double Adjustable - SBC / LS (1964-1967 GM A-Body) - 030306-DDS
Bring modern coilover performance and adjustability to your classic GM A-Body with the Detroit Speed 030306-DDS Front Coilover Conversion Kit. Designed specifically for 1964-1967 GM A-Body applications equipped with Small Block Chevrolet or LS engines, this direct bolt-in system replaces the conventional front spring and shock arrangement with Detroit Speed's double adjustable coilover setup. The result is extensive ride-height adjustment, performance-focused Detroit Tuned valving, and the ability to fine-tune shock behavior to match the car, driver, and intended use.
The 030306-DDS uses double adjustable aluminum-body coilover shocks that provide two independent adjustments and an extensive tuning range. This gives serious street and performance enthusiasts the ability to tailor shock response more precisely than a non-adjustable or single-adjustable setup while retaining excellent street ride quality. Whether you're dialing in a Pro-Touring A-Body for aggressive cornering or refining the balance of a high-performance street car, the double adjustable configuration provides the tuning capability needed to get more from the suspension.
Detroit Speed pairs the shocks with 550 pounds/inch coilover springs with a 9.5 inch free length for the SBC/LS application. Threaded spring adjusting nuts provide ride-height adjustment, while included thrust bearings and thrust washers help make spring adjustments easier. Detroit Speed also supplies its dedicated spanner tool so ride-height changes can be made using the proper adjustment tool.
The conversion is engineered as a direct bolt-in package and includes the components necessary for installation. In addition to two Detroit Tuned coilover shocks and two coilover springs, the kit includes spring adjusting nuts, polyurethane upper and lower shock bushings, aluminum spacers, thrust bearings, thrust washers, mounting hardware, and the Detroit Speed spanner tool. This integrated approach gives 1964-1967 A-Body owners a complete path to modern front coilover technology without piecing together unrelated suspension components.
For builders who want more than basic ride-height adjustment, the 030306-DDS delivers a substantial step up in suspension tuning capability. Its combination of Detroit Speed-developed valving, double adjustable shocks, application-specific spring rate, and comprehensive bolt-in hardware makes it an excellent foundation for a street-driven restomod, Pro-Touring build, or performance-focused classic GM A-Body.
