DSE Rear Coilover Conversion Kit - Double Adjustable Shocks - Stock Axle (042404-DDS) - 1964-1966 GM A-Body
Bring modern coilover adjustability and Detroit Speed suspension tuning to your classic A-Body with the Detroit Speed Rear Coilover Conversion Kit. Designed for 1964-1966 GM A-Body applications using the stock rear axle, part number 042404-DDS replaces the original separate rear coil spring and shock arrangement with an integrated coilover shock and spring package. The conversion gives you extensive ride-height adjustability along with Detroit Tuned shock valving, making it a serious upgrade for enthusiasts who want to sharpen the handling of a street-driven, pro-touring, autocross, or track-focused A-Body.
The 042404-DDS package steps up to Detroit Speed's double-adjustable shock configuration, providing two independent adjustments and a broad tuning range so shock performance can be tailored to the vehicle, driver, and intended use while retaining excellent street ride quality. The kit uses 175 pounds per inch coilover springs with an 11 inch free length and includes the upper and lower mounting hardware required to convert the factory rear suspension. Detroit Speed engineered the system as a complete bolt-on package, allowing modern coilover technology to be added without requiring a welded-in rear suspension conversion.
