Adding your products to cart

If your Kenworth W990 rides rough or feels unstable on uneven roads, your shocks could be worn out. Replacing them helps restore comfort, control, and safety, especially when hauling heavy loads over long distances.

Upgrade Your W990 Ride Comfort with Dampeners

Kenworth T800 shock absorbers and W990 shocks share similar heavy-duty performance. They're built to smooth out vibration, reduce bounce, and keep your truck steady through sharp turns or rough highways. Quality aftermarket shocks help your suspension do its job, keeping tires on the pavement and your cab riding level. When you change your shocks, don't overlook the small parts that make a big difference: - Shock bushings cushion vibration and prevent metal-to-metal wear. - Bolt kits and spacers keep the connection points tight and aligned. - Upper mounts and studs stop rattles and clunks under load. If you notice drifting, clunking, or extra sway, it's time to check your suspension setup. Replacing worn-out shocks and hardware will get your Kenworth W990 riding smooth and steady again. Browse our full lineup of aftermarket Kenworth W990 suspension, mounting hardware, Kenworth T800 front axle air ride kits and Kenworth T800 air springs to keep your truck performing the way it should.

Frequently Asked Questions About Kenworth W990 Shock Absorbers

Will these shock absorbers fit my Kenworth W990 without modification?

Shock absorbers in this category are designed to match the specific mounting configuration, length, and load requirements of the Kenworth W990. However, fitment can vary depending on axle position (front or rear), suspension type, and your truck's build year or trim. Always check the listed specifications and part numbers against your truck's OEM shock or service manual before ordering to confirm a proper fit.

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

Common signs of worn shock absorbers include excessive bouncing or cab sway, uneven tire wear, visible oil leakage on the shock body, or a rougher ride than usual. If you notice any of these symptoms, or if your shocks are original and have significant mileage on them, it is a good idea to inspect them and consider replacement to maintain ride quality and control.

Are these shock absorbers OEM or aftermarket, and does it matter?

Our catalog includes both OEM and quality aftermarket shock absorber options for the W990. OEM parts are built to match factory specifications exactly, while aftermarket options can offer comparable performance often at a different price point. The right choice depends on your budget, preference for factory-matched parts, and any specific performance characteristics you are looking for.

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

Shock absorber replacement is a common maintenance task that many experienced technicians and owner-operators handle themselves with basic tools and a lift or jack stands. That said, proper torque specs and safe vehicle support are important for a secure installation. If you are not comfortable with suspension work, having a qualified technician install them is a safe option.

Should I replace shock absorbers one at a time or in pairs?

It is generally recommended to replace shock absorbers in pairs (both sides of the same axle) even if only one appears worn or damaged. This helps maintain even handling and ride characteristics across the axle, since shocks tend to wear at a similar rate over time.
