Detroit Speed Coilover Front Conversion Kit - Base Shocks - SBC / LS (1968-1972 GM A-Body) - 030308DS
Bring modern coilover suspension technology to your classic GM A-Body with the Detroit Speed 030308DS Front Coilover Conversion Kit. Engineered for 1968-1972 GM A-Body applications with Small Block Chevrolet or LS engines, this direct bolt-in system delivers the ride-height adjustability and suspension control of a modern coilover package without requiring adjustable shock tuning. Detroit Speed combines application-specific springs with aluminum-body shocks featuring Detroit Tuned valving to give your classic more precise suspension performance while maintaining excellent street ride quality.
The 030308DS uses base non-adjustable aluminum-body coilover shocks with Detroit Tuned valving. Instead of requiring the driver to experiment with shock settings, Detroit Speed engineers the damping into the shock for a balanced combination of handling and ride quality. That makes this version an excellent choice for enthusiasts who want a straightforward coilover upgrade with proven valving and adjustable ride height without the added complexity of single or double adjustable shocks.
Detroit Speed pairs the shocks with 550 pounds/inch coilover springs with a 9.5 inch free length for the SBC/LS application. The threaded coilover design provides extensive ride-height adjustability, allowing you to dial in the front stance and suspension setup for your build. Thrust bearings and thrust washers are included to assist with spring adjustment, and the kit includes a Detroit Speed spanner tool for making coilover adjustments.
The 030308DS is engineered as a direct bolt-in 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, and the Detroit Speed spanner tool. The result is a complete, application-specific conversion designed to work together rather than requiring you to piece together unrelated shocks, springs, and mounting components.
Whether you're updating a Chevelle, GTO, Skylark, Cutlass, El Camino, or another compatible 1968-1972 GM A-Body, the Detroit Speed 030308DS provides a strong foundation for a modernized front suspension. Its combination of Detroit Tuned base shocks, 550 pounds/inch springs, adjustable ride height, and direct bolt-in installation makes it a smart choice for street performance, restomod, and Pro-Touring builds where predictable handling and straightforward setup matter.
