Valley Truck Parts has a large inventory of rebuilt differentials. ALL units have a Nationwide One Year Warranty and a "No Hassle" core return policy. Each unit is completely disassembled and rebuilt with 100% new bearings, seals, O-rings and any other part that does not meet our strict criteria. We have most units in stock and can ship nationwide the same day as ordered. We also have "Inspected Used and Core" differentials in stock. Please call for pricing and availability
