Good To Know

Q: Will this seal fit my Peterbilt 379 with aftermarket door skins? A: This weatherstrip is shaped to match the factory door pinch weld; light trimming may be required if the door edge profile has been modified.

Q: How is the seal installed? A: Press the push-on channel over the door flange starting at one corner and work around the perimeter; no adhesive or special tools are needed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
