Rear Sway Bars are manufactured from heavy duty solid-core (1045) high strength steel for maximum durability. The CNC forming ensures precision fitment of each application for a true bolt-on installation. Edelbrock engineers have designed these rear applications to allow removal of vehicle's rear differential cover with the sway bar fully installed. Like the front sway bars, some applications feature adjustable end links for fine tuning of the roll stiffness to your personal preference. They include greasable graphite polyurethane bushings on most applications, u-bolts and high quality zinc plated hardware.

Why did they choose different materials for the front and rear?

4130 Chromoly was chosen for the front sway bars for two simple reasons - weight and strength. A vehicle carries the majority of its weight in the front end and 70% of the braking is handled by the front brakes. The front end is also responsible for the vehicle's steering control. 4130 Chromoly provides the tensile strength (up to 130 pounds per square inch (Ksi) and its hollow-core design keeps weight to a minimum. This provides the optimal ratio of weight vs. strength to increase the chassis roll stiffness and improve handling without compromise. When Edelbrock engineered the rear sway bars, 1045 was the material best suited to provide the optimal roll stiffness. Since weight is not as critical to the rear of the vehicle, 1045's solid core provides strength and long-term durability. This all adds up to a great product at exceptional value to our customers.
