Rockwell Transmission Parts

Rockwell transmission parts and bearing kits, new, used and rebuilt, for trucks, tractors and heavy equipment.

We carry new, used and rebuilt Rockwell transmission parts for heavy, medium and light duty trucks, tractors, semis and heavy equipment. Rockwell's truck products later carried the Meritor name, so you will find these parts in our store under Meritor transmission parts.

Rockwell parts we stock

• Rebuild kits and seal kits
• Bearings and bearing kits
• Gears and shafts
• Splined parts and replacement hardware

If it is a gear in a Rockwell transmission, there is a good chance we have it on the shelf. Stock parts ship the same day, and we ship worldwide.

Finding the right part

Send us the model and serial number from the tag, any casting number on the case (like the one in the photo), or the part number off the failed part, and our truck parts experts will do the legwork to match it. They can also help with other transmission questions while you are on the phone.

Other makes

We stock parts for most heavy duty truck transmissions, not just Rockwell:

• Eaton Fuller transmission parts
• Spicer transmission parts
• Mack transmission parts

Or browse all transmission parts in the online store. If you would rather replace the whole unit, see rebuilt Rockwell transmissions.
