Forged from the highest quality steel, each torsion bar is centerlessly ground to provide a constant spring rate, chemically coated to protect against rust and then matched in pair sets to ensure that both sides of the car are equally suspended. Guaranteed for 3 years against breakage. Note: worn torsion bar bushings will shorten the life of torsion bars. Our 3-year guarantee will remain valid only when bushings are in good condition at time of installing new torsion bars. Sold in pairs.
