Our 1941-46 Chevy Truck and GMC Truck Tapered Roller Bearing Conversion kit is used to convert the old style ball bearings to the much more advanced tapered roller bearing. Tapered roller bearings control side loads better and disperse heat quicker than the old original ball bearings. We highly recommend this kit for your original straight axle front end. Kit includes: • Inner Bearings • Outer Bearings • Races • Seals
