The OE plastic Torsion Spring Retainer over-stresses causing failure, its one of the weakest parts of your differential. SANDCRAFT redesigned and doubled the engagement surface areas using billet aluminum, with internal and external engagement properties that raise the bar in durability and dynamic loads. Each Billet Torsion Spring Retainer comes with a pre-installed hardened spring retaining dowel pin.
