Detroit Speed Coilover Front Conversion Kit - Base Shocks - BBC (1964-1967 GM A-Body) - 030307DS
Bring modern coilover suspension technology to your big-block classic with the Detroit Speed 030307DS Front Coilover Conversion Kit. Engineered specifically for 1964-1967 GM A-Body applications with Big Block Chevrolet engines, this direct bolt-in package replaces the conventional front spring and shock arrangement with an integrated coilover system. Detroit Speed combines extensive ride-height adjustability with application-specific Detroit Tuned valving to deliver improved suspension control and excellent street ride quality without requiring adjustable shocks.
The 030307DS uses aluminum-body non-adjustable coilover shocks featuring Detroit Tuned valving. Rather than requiring the driver to experiment with shock settings, the base package uses Detroit Speed-developed valving to provide a predetermined balance of ride quality and performance. This makes the kit an excellent choice for enthusiasts who want the handling, packaging, and ride-height benefits of a modern coilover conversion without the additional setup involved with single or double adjustable dampers.
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 threaded coilover design provides extensive ride-height adjustment, giving you the ability to dial in the front stance while retaining a matched shock and spring package. Included thrust bearings and thrust washers help make spring adjustments easier, and Detroit Speed supplies a dedicated spanner tool for making coilover adjustments.
The 030307DS is designed as a direct bolt-in front coilover conversion and includes the necessary components for installation. The package includes two Detroit Tuned coilover shocks, two coilover springs, spring adjusting nuts, polyurethane upper and lower shock bushings, aluminum spacers, thrust bearings, thrust washers, mounting hardware, and the Detroit Speed spanner tool. Instead of piecing together unrelated suspension 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 improved suspension control and adjustable stance without the complexity of adjustable shock tuning, the Detroit Speed 030307DS delivers a straightforward performance upgrade. Its combination of BBC-specific 650 pounds/inch springs, Detroit Tuned base shocks, extensive ride-height adjustment, and complete bolt-in hardware makes it an excellent foundation for a street-driven restomod or Pro-Touring build.
