DSE Rear Tubular Sway Bar Kit (042202DS) - 1973 - 1977 GM A-Body
Sharpen the handling of your 1973-1977 GM A-Body with the DSE Rear Tubular Sway Bar Kit 042202DS. Unlike the factory-style rear sway bar arrangement that mounts between the lower control arms, Detroit Speed engineered this system to connect the rear axle housing directly to the chassis crossmember. Using the chassis to stabilize the rear axle helps minimize deflection under heavy cornering loads, giving your classic A-Body a more controlled and confidence-inspiring feel when you start pushing it through the turns.
The heart of 042202DS is a 1-1/8-inch tubular sway bar manufactured from 520 DOM tubing. Detroit Speed combines it with patented Swivel-Link end links that allow the bar to articulate freely throughout rear suspension travel while eliminating bind. Two adjustment positions let you tune rear roll stiffness to suit the car and driving style, with a 597 pounds per inch rate at the front hole and a firmer 736 pounds per inch rate at the rear hole. Finished in black powder coat, the complete bolt-on package includes the sway bar, polyurethane bushings, Swivel-Link end links, mounting brackets, axle clamps, U-bolts, lock collars, and required installation hardware.

FAQs
What makes DSE 042202DS different from a factory-style A-Body rear sway bar?
Instead of mounting between the lower control arms, the Detroit Speed sway bar connects the rear axle housing to the chassis crossmember. This uses the chassis to stabilize the rear axle and helps minimize deflection when the car is subjected to heavy cornering loads.
Is the DSE 042202DS rear sway bar adjustable?
Yes. The bar provides two adjustment positions. Detroit Speed specifies a 597 pounds per inch rate at the front hole and a firmer 736 pounds per inch rate at the rear hole, allowing you to tune rear roll stiffness for your setup.
What is included with DSE 042202DS?
The kit includes the tubular rear sway bar, polyurethane bushings, bushing mounts, grease caps, Swivel-Link end links, left- and right-side end-link mounting brackets, lower axle mounting clamps, U-bolts, split lock collars, and associated installation hardware.
