Kenworth W900A Leaf Springs, Hangers & Acc.

Frequently Asked Questions About Kenworth W900A Leaf Springs, Hangers & Acc.

Will these leaf springs and hangers fit my Kenworth W900A?

Fitment depends on your truck's axle position, capacity rating, and suspension configuration, which can vary by model year and build. Always check the listed specifications against your truck's original components or your build sheet, and reach out to our parts team if you're unsure before ordering.

What is the difference between a leaf spring and a hanger, and do I need both?

The leaf spring is the curved metal assembly that supports the axle and absorbs road shock, while the hanger is the bracket that mounts the spring to the frame. If you're replacing a worn or cracked spring, the hanger may still be serviceable, but it's worth inspecting both for wear, rust, or elongated bolt holes before deciding what to replace.

What are common signs that a leaf spring or hanger needs to be replaced?

Watch for uneven ride height, a sagging axle, clunking or squeaking noises over bumps, visible cracks in the spring leaves, or a bent or corroded hanger bracket. Worn bushings at the hanger connection can also cause excess play and should be checked during any suspension inspection.

Can I install these parts myself, or should I have a professional do it?

Leaf spring and hanger replacement involves working under a loaded truck frame with heavy components under tension, so it should only be attempted by someone with the proper lift equipment, spring compressors, and mechanical experience. Most shops recommend having this job done by a qualified technician to ensure everything is torqued and aligned correctly.

What materials and finishes are available for these components?

Leaf springs are typically made from heat-treated steel alloy for durability under heavy loads, while hangers are usually cast or forged steel. Finish options can include raw steel, primed, or painted/coated versions for added corrosion resistance, so check the product listing for the specific finish included with your part.
