Axle side play is one of the leading causes of poor handing and stability in trucks, particularly while carrying a heavy load or while pulling a trailer. Lateral forces generated by cornering or side winds cause the leaf springs to deflect, creating a "tail wagging the dog" sensation. Henderson's SuperSteer Trac Bar clamps to the rear axle housing on the passenger side, and bolts to the frame on the driver¹s side, positively locating the rear axle. The result is vastly improved handling and stability. Designed to fit '04-'08 Dodge Heavy Duty trucks, this SuperSteer Trac Bar bolts in place with no drilling or welding required.
