Peterbilt 389 Glider Clamps, Brackets & Mounting

Frequently Asked Questions About Peterbilt 389 Glider Clamps, Brackets & Mounting

What exactly are glider clamps, brackets, and mounting components used for?

These parts are the hardware used to secure and position various components on a Peterbilt 389 glider chassis, such as brackets for exhaust systems, air cleaners, fenders, fuel tanks, and other body or chassis-mounted accessories. Since glider kits are often built or reassembled outside a standard factory line, having the correct clamps and brackets ensures everything is mounted securely and in the proper location.

Will these clamps and brackets fit my specific Peterbilt 389 glider build?

Fitment can vary depending on your truck's configuration, including cab style, chassis length, and which components you are mounting. We recommend checking the listed specifications and measurements on each product page and comparing them to your current setup before ordering. If you are unsure, our team can help confirm fitment based on your truck's build details.

What materials are these clamps and brackets made from, and how well do they hold up?

Most clamps and brackets in this category are made from durable steel or stainless steel, often with a protective finish such as powder coating, zinc plating, or polished stainless to resist rust and corrosion. Stainless steel options are generally preferred for long-term durability, especially in areas exposed to road salt, moisture, and general wear.

Do I need any special tools or professional help to install these parts?

Basic hand tools such as wrenches and sockets are typically sufficient for installing most clamps and brackets. However, because these components are often tied into structural or safety-related systems like exhaust or fender mounting, we recommend having the installation checked by someone experienced with glider builds if you are not fully familiar with the process, to make sure everything is torqued and aligned correctly.

Are these parts designed to meet OEM specifications, or are they aftermarket replacements?

Many of the clamps and brackets in this category are designed to match OEM dimensions and mounting points so they integrate cleanly with a factory-style Peterbilt 389 setup. That said, some items are aftermarket parts built to fit common configurations rather than exact OEM part numbers, so it is a good idea to compare specs closely if exact OEM matching is required for your build.
