Mopar Performance Parts has re-released these previously discontinued A-833 four-speed front bearing retainers. No more scouring the salvage yards for the correct one. Whether you are swapping transmissions or restoring a legend, you can choose the correct bearing retainer for your application. Each package includes the retainer, retainer gasket and input shaft seal. Bearing retainers are identified by their outside diameter (O.D.) attaching bolt circle diameter (B.C.), and corresponding transmission input shaft.
