Frequently Asked Questions About Peterbilt 389 Glider Leaf Springs, Hangers & Acc.

Will these leaf springs and hangers fit my Peterbilt 389 Glider?

Fitment on a Peterbilt 389 Glider can vary depending on the axle configuration, suspension setup, and the specific chassis build, since glider kits are often assembled with components from multiple manufacturers. Before ordering, check the part number against your truck's build sheet or VIN specifications, and reach out to our parts team if you need help confirming compatibility with your specific setup.

What materials are these leaf springs and hangers made from, and how durable are they?

Leaf springs are typically made from heat-treated spring steel designed to handle repeated flexing and heavy loads, while hangers are commonly cast or forged steel for strength under constant stress. Look at the product listing for specific material details, since durability can vary between OEM-style and aftermarket options.

Do these parts come with a protective coating or finish?

Many leaf springs and hangers are available with a painted, powder-coated, or raw steel finish depending on the manufacturer. A protective finish helps resist corrosion from road debris, moisture, and salt exposure, so it is worth checking the product description to see what finish is included before you buy.

What tools or equipment do I need to install new leaf springs or hangers?

Replacing leaf springs and hangers is a heavy-duty job that typically requires a shop press or hydraulic jack stands, a torque wrench, and impact tools to safely remove and install the assembly. Because these components support the weight of the truck, this installation is best handled by an experienced technician or a shop with the proper lift and safety equipment.

How do I know if my leaf springs or hangers need to be replaced?

Common signs include sagging ride height, uneven tire wear, cracked or broken leaves, excessive bouncing, or visible rust and wear at the hanger mounting points. If you notice any of these symptoms, it is a good idea to have your suspension inspected so you can determine whether springs, hangers, bushings, or related hardware need replacement.
