DSE Rear QuadraLink Sway Bar Kit - 3/4 Inch (042218DS) - 1970-1981 Chevrolet Camaro / Pontiac Firebird
Fine-tune the rear suspension of your second-gen F-Body with the Detroit Speed Rear QuadraLink Sway Bar Kit. Designed specifically for 1970-1981 Chevrolet Camaro and Pontiac Firebird models equipped with the Detroit Speed QuadraLink rear suspension, part number 042218DS uses a 3/4 inch adjustable rear sway bar to help reduce body roll and deliver more predictable handling. It is a purpose-built upgrade for drivers who want additional control over chassis balance without unnecessarily sacrificing ride quality.
The two-position design gives you a useful range of rear roll stiffness for dialing in the car around your suspension combination and driving style. The front mounting hole provides a 312 pounds per inch sway bar rate, while the rear hole increases the rate to 414 pounds per inch. A gloss black powder-coated finish provides lasting protection and a clean appearance, while the included end links, bushings, and mounting brackets provide the key components needed to integrate the bar with a Detroit Speed QuadraLink-equipped F-Body.
