DSE Rear Coilover Conversion Kit - Double Adjustable Shocks - Stock Axle (042405-DDS) - 1968-1972 GM A-Body
Transform the rear suspension of your classic A-Body with modern coilover technology and serious shock-tuning capability. The Detroit Speed Rear Coilover Conversion Kit, part number 042405-DDS, is engineered for 1968-1972 GM A-Body applications using the stock rear axle. This complete bolt-on package replaces the original separate rear coil spring and shock combination with an integrated Detroit Tuned coilover system, giving you extensive ride-height adjustment along with the suspension control needed for a properly sorted street-performance, pro-touring, autocross, or track build.
The 042405-DDS package features Detroit Speed's double-adjustable shock configuration with two independent adjustments and a wide tuning range. This allows the shocks to be dialed in for the demands of the vehicle and driver while retaining excellent street ride quality. Detroit Speed pairs the shocks with 175 pounds per inch coilover springs measuring 11 inches in free length. Application-specific upper mounting plates, lower coilover brackets, spacers, and a Detroit Speed/JRi spanner tool complete a system engineered to bolt onto the A-Body chassis and stock rear axle.
