DSE Rear Coilover Conversion Kit - Double Adjustable Shocks - Stock Axle (042406-DDS) - 1967 GM A-Body
Give your 1967 GM A-Body the suspension control and adjustability of a modern coilover setup with the Detroit Speed Rear Coilover Conversion Kit. Part number 042406-DDS is engineered specifically for 1967 GM A-Body applications using the stock rear axle and replaces the original separate rear coil spring and shock combination with an integrated Detroit Tuned coilover package. The result is extensive ride-height adjustability and a more tunable rear suspension for enthusiasts looking to get more out of a serious street-performance, pro-touring, autocross, or track-focused build.
The 042406-DDS package features Detroit Speed's double-adjustable shock configuration. With two independent adjustments and an extensive adjustment range, these shocks give experienced tuners the ability to tailor damping to the demands of the car, driver, and intended use while maintaining 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 and lower coilover mounts, spacers, hardware, and a Detroit Speed/JRi spanner tool complete a bolt-on conversion engineered as a system rather than a collection of universal suspension parts.
