Kenworth T680 Shock Absorbers

Frequently Asked Questions About Kenworth T680 Shock Absorbers

Will these shock absorbers fit my Kenworth T680?

Shock absorbers for the T680 vary by axle position (front or rear) and by the model year and suspension configuration of your truck. Always check the listed specifications, part number, and application notes for each product against your truck's VIN or existing shock dimensions before ordering to confirm a proper fit.

How do I know when my shocks need to be replaced?

Common signs of worn shock absorbers include excessive bouncing or vibration in the cab, uneven tire wear, longer stopping distances, visible fluid leaking from the shock body, or a rougher, less controlled ride than usual. If you notice any of these symptoms, it's a good idea to have the shocks inspected and replaced as needed.

Can I replace the shock absorbers myself, or should I have a professional do it?

Replacing shock absorbers is a common maintenance task that many experienced technicians handle in-house, but it does require proper tools, jack stands, and torque specifications to ensure the shocks are mounted securely. If you're not comfortable working under a raised truck or don't have the right equipment, having a qualified technician perform the installation is recommended.

Should I replace shocks in pairs or all at once?

Most manufacturers and fleet maintenance guidelines recommend replacing shocks in pairs (both front or both rear) at the same time, even if only one appears worn. This helps maintain even ride control and handling on both sides of the axle, since shocks tend to wear at a similar rate over time.

What's the difference between OEM and aftermarket shock absorbers for the T680?

OEM shock absorbers are built to match the original specifications Kenworth used on the T680, while aftermarket options may offer different valving, materials, or price points. Both can be reliable choices, but it's important to compare load ratings, mounting style, and application fitment to make sure the replacement performs similarly to what your truck came with.
