Heavy-Duty Truck Transmission Parts
Not sure which part you need? Use our parts-request checklist.
Keep your Class 8 trucks shifting and on the road with heavy-duty truck transmission parts built for over-the-road and vocational duty. JAK'S Diesel stocks rebuild and service components for manual heavy-duty truck transmissions: shafts, gears, synchronizers, bearings, seals, shift forks, and gaskets.
Not sure of the exact part on your unit? Give us the transmission make and model or the number stamped on the case and we will cross-reference OEM, competitor, and superseded numbers to get you the right component. Most orders ship same-day, with free freight over $1,000.
Browse transmission bearings for the mainshaft, countershaft and other verified transmission applications.
