DSE Rear Coilover Conversion Kit - Single Adjustable Shocks - Stock Axle (042404-SDS) - 1964-1966 GM A-Body
Give your classic A-Body modern rear suspension adjustability without abandoning its proven factory suspension architecture. The Detroit Speed Rear Coilover Conversion Kit, part number 042404-SDS, converts 1964-1966 GM A-Body models with a stock rear axle from the original separate coil spring and shock arrangement to an integrated coilover shock and spring package. Extensive ride-height adjustment lets you dial in stance and suspension setup, while Detroit Tuned valving is engineered to deliver the combination of handling control and street ride quality expected from a serious performance build.
The 042404-SDS package adds single-adjustable shocks to Detroit Speed's A-Body coilover system. These shocks retain the features and Detroit Tuned valving of the base package while adding rebound adjustment through an easily accessible knob. That gives you the ability to fine-tune shock response for the way the car is driven without stepping up to a more complex multi-adjustable package. Detroit Speed pairs the shocks with 175 pounds per inch springs measuring 11 inches in free length and supplies the application-specific upper and lower mounting components needed for the bolt-on conversion.

FAQs
What adjustment does the Detroit Speed 042404-SDS shock provide?
The single-adjustable shocks add rebound adjustment to Detroit Speed's base shock features and Detroit Tuned valving. Rebound can be adjusted using a knob, allowing shock response to be fine-tuned for the vehicle and driving conditions.
How is 042404-SDS different from 042404DS?
Both kits are designed for 1964-1966 GM A-Body applications with the stock rear axle and use 175 pounds per inch springs. The 042404DS package uses Detroit Speed's base non-adjustable shocks, while 042404-SDS adds adjustable rebound damping.
Does Detroit Speed 042404-SDS require welding?
No. Detroit Speed describes its A-Body rear coilover conversion as a complete bolt-on package and supplies the application-specific upper and lower mounting components required to replace the existing rear coil spring and shock combination.
