Winters Sprint Torsion Arm - Right Rear - 13-1/4" x 4-1/2" Bend - 2024-T3 Billet Aluminum

Heavy duty styles are for racers that "feel" the arms flex under load. Contact patch under the arm is rounded to prevent premature arm wear. Torsion arms are solid from the bend to the back of the rear arm to help reduce flexing. Winters is the ONLY ONE to offer this feature. Winters rear arms are the ONLY ONES to offer a light press fit on the shock bolt mounting area. 100% machined surface. 10° angle broach makes wheel rate stiffer.
