Detroit Speed Coilover Front Conversion Kit - Double Adjustable Shocks - SBC / LS (1968-1972 GM A-Body) - 030308-DDS
Bring modern coilover performance and serious suspension tuning capability to your classic GM A-Body with the Detroit Speed 030308-DDS 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. Extensive ride-height adjustability, Detroit Tuned valving, and double adjustable shocks give performance-minded builders the ability to dial in both stance and suspension response while maintaining excellent ride quality on the street.
The 030308-DDS features double adjustable aluminum-body coilover shocks with two independent adjustments and an extensive tuning range. This additional control allows the shocks to be tailored to the demands of the vehicle, driver, and intended use. Whether you're setting up a street-driven restomod, carving corners in a Pro-Touring build, or looking for greater control during competitive driving, the double adjustable configuration provides substantially more tuning capability than a fixed-valving or single 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 adjustment, giving you the ability to fine-tune the front stance while retaining an integrated shock and spring package. The conversion also includes thrust bearings and thrust washers to assist with spring adjustment along with a Detroit Speed spanner tool for making coilover adjustments.
The 030308-DDS is engineered as a direct bolt-in conversion and includes the components necessary for installation. Detroit Speed supplies two Detroit Tuned coilover shocks, two coilover springs, spring adjusting nuts, rubber insulators, thrust bearings, thrust washers, mounting hardware, and a dedicated spanner tool. The result is a complete package engineered specifically for the 1968-1972 GM A-Body rather than a collection of unrelated suspension components.
For a Chevelle, GTO, Skylark, Cutlass, El Camino, or other compatible GM A-Body that needs modern suspension control and extensive adjustability, the Detroit Speed 030308-DDS delivers a major upgrade. Its combination of SBC/LS-specific 550 pounds/inch springs, adjustable ride height, Detroit Tuned valving, and double adjustable shocks gives serious enthusiasts the flexibility to tune their suspension around the way the car is actually built and driven.
