DSE Rear Coilover Conversion Kit - Base Shocks - Stock Axle (042405DS) - 1968-1972 GM A-Body
Upgrade your classic GM A-Body with modern coilover suspension technology using the Detroit Speed Rear Coilover Conversion Kit. Designed for 1968-1972 GM A-Body applications with the stock rear axle, part number 042405DS replaces the original separate rear coil spring and shock arrangement with an integrated Detroit Tuned coilover shock and spring package. The conversion gives you extensive rear ride-height adjustability while providing a performance-oriented suspension foundation engineered to improve the handling and ride of your classic muscle car.
The 042405DS package is Detroit Speed's base shock version, making it an excellent choice for enthusiasts who want the benefits of a properly engineered coilover system without the additional complexity of adjustable shock valving. The non-adjustable shocks feature Detroit Tuned valving and are paired with 175 pounds per inch springs with an 11 inch free length. Detroit Speed engineered the conversion as a complete bolt-on package and includes the application-specific upper and lower shock mounting components, spacers, coilover springs and shocks, and a Detroit Speed/JRi spanner tool needed for the conversion.
