Product Overview

A cab door that rattles, needs to be slammed, sits proud of the body, or will not latch consistently may be closing on a worn or misaligned striker. This pair lets both doors be serviced together on compatible Peterbilt cabs.

Striker adjustment cannot correct every door problem. Check hinge pins, latch jaws, cab mounts, and sheet-metal alignment before setting the new pins.

Q: Does it fit newer Peterbilt trucks? A: The verified coverage is for compatible 2005-and-older applications.

Q: How tight should the door close? A: It should latch securely without needing a slam or placing side load on the latch.
