SuperSprings Self-Adusting Suspension Stabilizers
Unlike other helper springs that harded the ride by using a U-Bolt to rigidly attach to the factory springs, SuperSprings patented roller and shackle system allows the extra support to only kick in when required. This ensures a smooth ride whether loaded or unloaded. * Never needs adjusting like "air systems". * Anto-sway feature increases handling stability * Increases the life of brakes, tires & existing suspension.
