Peterbilt 367 Leaf Springs, Hangers & Acc.

Frequently Asked Questions About Peterbilt 367 Leaf Springs, Hangers & Acc.

How do I know which leaf springs and hangers fit my Peterbilt 367?

Fitment depends on your truck's axle position, spring capacity rating, and whether the springs are for the front or rear suspension. Always check the part number against your truck's build sheet or VIN, and compare spring length, arch, and leaf count to your current setup before ordering. If you are unsure, our sales team can help match components to your truck's specifications.

What are the signs that my leaf springs or hangers need to be replaced?

Common signs include a sagging or uneven ride height, cracked or broken leaves, excessive body roll, unusual noises like clunking or squeaking over bumps, and visible rust or wear on the hanger brackets and bushings. If you notice any of these issues, it is a good idea to inspect the entire suspension assembly, since a worn hanger or bushing can accelerate wear on the springs themselves.

Can I replace just one leaf spring or hanger, or should I do both sides?

While it is possible to replace a single damaged spring or hanger, many fleet managers and drivers prefer to replace both sides at the same time to maintain even ride height and handling. Mixing old and new components can sometimes lead to uneven wear, so consider the age and condition of the opposite side before deciding.

What material and finish options are available for these parts?

Leaf springs are typically made from heat-treated alloy steel for durability under heavy loads, while hangers and brackets are often steel with options like painted, powder-coated, or raw finishes depending on the manufacturer. Choosing a corrosion-resistant finish can help extend the life of the part, especially in regions with harsh weather or road salt exposure.

Do I need any special tools or professional help to install leaf springs or hangers?

Replacing leaf springs and hangers is a heavy-duty job that typically requires a lift or jack stands rated for the truck's weight, along with common hand tools and possibly an air hammer for stubborn bolts or bushings. Because these components are critical to safe handling and load support, many owners choose to have installation done by a qualified technician, particularly for hanger and bushing replacement where proper torque specs matter.
