Peterbilt 389 Glider Mirrors & Acc.

Frequently Asked Questions About Peterbilt 389 Glider Mirrors & Acc.

Will these mirrors and mirror accessories fit my Peterbilt 389 glider kit truck?

Most mirrors and mirror components in this category are designed to fit the Peterbilt 389, but glider kit trucks can have variations in cab configuration and mounting setups depending on when and how the glider was built. Before ordering, check the specific mounting style (hood-mount, door-mount, or cowl-mount) and compare it to what is currently on your truck to confirm a proper fit.

What is the difference between the mirror head, mirror arm, and mounting bracket, and do I need to replace all of them?

The mirror head is the glass and housing assembly, the arm connects the head to the truck, and the bracket secures the arm to the cab or hood. If only one component is damaged or worn, you typically do not need to replace the entire assembly. Many customers replace just the mirror head or arm to save on cost, as long as the remaining parts are in good condition and compatible.

Are heated and powered mirrors available, and how do they wire into the truck?

Yes, many mirror options include heated glass and power adjustment features. These typically connect to your truck's existing wiring harness if the truck was originally equipped with heated or powered mirrors. If you are upgrading from manual mirrors, you may need additional wiring or a compatible switch, so it is worth checking your cab's current electrical setup before purchasing.

What finish options are available, and how do I keep the mirrors looking good over time?

Mirror arms and brackets are commonly available in chrome, stainless steel, or black finishes to match the rest of your truck's exterior. Chrome and stainless components hold up well with regular washing, but road grime, salt, and debris can dull the finish over time if not cleaned periodically. A basic metal polish designed for chrome or stainless will help maintain shine and prevent pitting.

How difficult is it to install a replacement mirror or mirror arm myself?

Most mirror heads and arms are designed for straightforward bolt-on installation using the existing mounting points on your truck. Basic hand tools are usually sufficient for the job. If your setup includes heated or powered features, you will also need to reconnect the wiring harness, which may require some basic electrical knowledge or a wiring diagram specific to your truck.
