DSE Rear 1.5 Inch Drop Coil Springs (041807PDS) - 1973 - 1977 GM A-Body
Give your 1973-1977 GM A-Body a more aggressive Pro-Touring stance while improving rear suspension performance with Detroit Speed Rear Drop Coil Springs. DSE 041807PDS lowers the rear approximately 1.5 inches from stock, helping reduce the factory ride height while delivering improved ride and handling compared with the soft original rear coils. For a performance street car, restomod, or Pro-Touring build, these springs provide a purpose-engineered way to improve both stance and suspension response.
Detroit Speed specifies a 150 pounds per inch spring rate and 15.75-inch free length for 041807PDS. Rather than lowering the car for appearance alone, these springs are engineered to provide a more performance-focused suspension setup while maintaining street-friendly ride characteristics. They are supplied as a pair for replacing both rear springs together and are designed specifically for 1973-1977 GM A-Body applications, excluding wagons.
