Peterbilt 389 Glider Front Axle Air Ride Kits

Frequently Asked Questions About Peterbilt 389 Glider Front Axle Air Ride Kits

What exactly is included in a front axle air ride kit?

A front axle air ride kit typically includes the air spring(s), mounting brackets, height control valve, air lines and fittings, and the hardware needed to convert or replace the front suspension components on a Peterbilt 389 glider kit build. Some kits may also include shock mounts or U-bolts depending on the specific application, so it's a good idea to review the parts list on each product page before ordering.

Will this kit fit my specific Peterbilt 389 glider chassis?

Fitment can vary based on the frame width, axle manufacturer, and the specific glider kit configuration used by the builder. Because glider kits are often assembled with a mix of components from different suppliers, we recommend confirming axle specs, frame dimensions, and mounting points against the kit details before purchasing. If you're unsure, our team can help you verify compatibility using your build sheet or axle information.

Do I need professional installation, or can this be done in my own shop?

Many owner-operators and shops with suspension experience install these kits themselves, but proper alignment, torque specs, and air line routing are critical for safe operation. If your shop is comfortable with front suspension work and has the necessary tools, installation is straightforward. If not, we recommend having the work done by a qualified diesel or suspension shop to ensure everything is set up correctly.

What's the difference between the air ride options available, and how do I choose the right one?

Front axle air ride kits can vary in air spring style, load capacity, and ride height design. The right choice depends on your axle weight rating, how the truck will be used, and the ride quality you're looking for. Reviewing the load ratings listed on each kit and comparing them to your front axle's GAWR will help narrow down the correct option.

How do I maintain the air ride system once it's installed?

Routine maintenance includes checking air lines and fittings for leaks, inspecting the air springs for cracking or wear, and making sure the height control valve is functioning properly. Keeping the system free of moisture buildup in the air lines and periodically checking mounting hardware for tightness will help extend the life of the kit.
