Gear Shop

Whether you are looking for a new, rebuilt, used or core transmission, differential, transfer case or auxiliary transmission, Specialty Truck Parts can fill your needs. Our veteran builders completely disassemble every unit they build. All gears, syncros, cases and covers are carefully inspected saving only the very best parts that meet our quality standards. Disassembling their own units guarantees fewer errors resulting in a higher quality rebuilt unit. All rebuilt units are reassembled complete with covers using all new bearings, seals, o-rings, gaskets and a fresh coat of paint.
