Freightliner SD 108-122 Shock Absorbers

Frequently Asked Questions About Freightliner SD 108-122 Shock Absorbers

Will these shock absorbers fit my Freightliner SD 108 or SD 122 model?

Shock absorbers for the Freightliner SD 108-122 series are designed to match the front and rear suspension setups used on these models, but fitment can vary based on axle position, cab configuration, and production year. Always check the part number against your truck's VIN or existing shock absorber before ordering, and reach out to our parts team if you're unsure which application applies to your specific unit.

How do I know if my current shock absorbers need to be replaced?

Common signs of worn shock absorbers include excessive bouncing or swaying, uneven tire wear, visible fluid leaks on the shock body, or a rougher ride than usual. If you notice any of these symptoms, or if your truck has accumulated significant mileage since the last replacement, it's a good idea to inspect the shocks closely or have them checked during your next service interval.

Are these shock absorbers designed for a specific position, such as front or rear?

Yes, shock absorbers are typically application-specific and built for either front or rear installation based on the load and suspension geometry of that position. Make sure to confirm whether you need a front or rear shock absorber before purchasing, as they are not usually interchangeable between positions.

What's involved in replacing a shock absorber on these trucks?

Replacing a shock absorber generally involves securing the vehicle, removing the upper and lower mounting bolts, and swapping in the new unit with the correct hardware. While many experienced technicians and fleet mechanics handle this job in-house, proper torque specs and mounting orientation matter, so consult your service manual or a qualified technician if you're not familiar with the process.

Do these shock absorbers come with a warranty, and what's the expected lifespan?

Warranty coverage varies by manufacturer and part, so check the specific product listing for warranty details before purchasing. Lifespan depends heavily on operating conditions, load weights, and road surfaces, but shock absorbers are a wear item that most fleets and owner-operators plan to replace periodically as part of routine suspension maintenance.
