Frequently Asked Questions About Kenworth Cabover Leaf Springs, Hangers & Acc.

How do I know if a leaf spring or hanger will fit my Kenworth cabover model?

Kenworth cabover models such as the K100 and T600/T800 cabover variants often used different suspension configurations depending on year and axle setup. Before ordering, check your truck's VIN, axle capacity, and existing spring dimensions (length, arch, number of leaves) against the part specifications listed on the product page. If you're unsure, our parts specialists can help confirm fitment using your truck's VIN or model information.

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

Common indicators include sagging or uneven ride height, cracked or broken leaves, excessive bouncing, clunking or squeaking noises over bumps, and visible rust or corrosion on the spring pack or hanger brackets. Worn bushings in the hangers can also cause noticeable play or misalignment in the suspension.

Can I replace just one leaf spring or hanger, or should they be replaced in pairs/sets?

While it's possible to replace a single damaged leaf or hanger, most experienced technicians recommend replacing springs in pairs (left and right) to maintain even ride height and load distribution. If one side has failed due to age or fatigue, the opposite side is often close behind. Hangers should be inspected on both sides as well, since uneven wear can affect alignment and tire wear.

What materials and finishes are available for these leaf springs and hangers?

Leaf springs are typically made from heat-treated alloy steel for durability under heavy loads, while hangers are commonly cast or forged steel. Finish options vary by manufacturer and part, ranging from raw steel to powder-coated or zinc-plated finishes for added corrosion resistance. Check the individual product listing for specific material and finish details.

Do I need any special tools or professional help to install a leaf spring or hanger kit?

Leaf spring and hanger installation typically requires a heavy-duty jack or lift, torque wrench, and hand tools, along with the ability to safely support the truck's frame and axle during the swap. Because these components are critical to load-bearing and steering stability, many owners choose to have installation performed by a qualified truck repair shop, especially if alignment or ride height adjustments are needed afterward.
