DOORS

Doors For Peterbilt Trucks

A damaged or deteriorated cab door affects far more than appearance — it compromises weather sealing, driver security, and cab noise levels on long hauls. Whether you need a complete replacement door assembly after collision damage or individual components like hinges, latches, and window regulators, we carry doors and door hardware for Peterbilt trucks including the 379, 389, 567, and 579 series.

Frequently asked questions about doors

Are Peterbilt door assemblies model-specific?

Yes. Door dimensions, hinge locations, and mirror mounting points vary between Peterbilt cab generations. The classic long-hood 379/389 series uses a different door than the aerodynamic 579 or the 567 vocational model. Always confirm the model, cab type (day cab vs. sleeper), and year range when ordering a replacement door to ensure correct fitment without modification.

Can I replace just the door skin instead of the entire door assembly?

In many cases, yes — especially for collision damage that affects the outer skin but leaves the door frame, hinges, and internals intact. Door skins can be welded or bonded to the existing frame in a body shop setting, which is often more cost-effective than a full door replacement. However, if the door frame is bent or the impact affected the latch and hinge areas, a full assembly replacement is typically the cleaner repair.

What causes Peterbilt door seals to fail, and how do I know when to replace them?

Door seals degrade from UV exposure, compression set from years of door closings, and ozone cracking. Signs of a failing seal include wind noise at highway speed, water intrusion around the door perimeter, and visible cracking or tearing in the rubber. A simple test is to close the door on a piece of paper — if it pulls out easily with no resistance, the seal has lost its compression and should be replaced.
