Adding your products to cart

If your Freightliner Century 112 or 120 rides rough, leans in corners, or bounces more than it should, your shocks may be worn out. Replacing them helps restore control, comfort, and stability, keeping your truck smooth and steady mile after mile.

Upgrade Your Freightliner Shock Dampeners for Better Performance

Aftermarket Freightliner Century 112 and 120 shocks are built for heavy-duty performance. They absorb road impact, reduce vibration, and help protect your suspension and tires from extra wear. Choose from steer, drive, or trailer shocks made with durable materials, double-lip seals, and corrosion-resistant finishes for long-lasting reliability. Trusted brands like Bulldog, Gabriel, and Monroe deliver dependable replacements that fit right and perform under load. When installing new shocks, check your mounting hardware and bushings too: - Bushings help cushion vibration and prevent metal-on-metal contact. - Bolt kits and spacers keep alignment tight and secure. - Upper mounts and studs stop rattling and looseness under heavy loads. If you notice extra bounce, uneven tire wear, or harsh vibration in the cab, it's time for fresh shocks, Freightliner Century 112 and 120 air springs or a Freightliner Century 112 and 120 front axle air ride kit. Keep your truck riding smooth with reliable shock dampeners and mounting components built for commercial use.

Frequently Asked Questions About Freightliner Century 112/120 Shock Absorbers

Will these shock absorbers fit my Freightliner Century 112 or 120?

Shock absorbers for the Century 112/120 vary depending on the model year, axle position (front or rear), and original suspension setup on your truck. Always check the length, mounting configuration, and bushing type against your existing shock or your truck's build sheet before ordering to ensure a correct fit.

How do I know when it's time to replace my shocks?

Common signs include excessive bouncing or cab sway, uneven tire wear, visible oil leaking from the shock body, worn or cracked bushings, and a rougher-than-normal ride quality. If you notice any of these symptoms, it's a good idea to inspect the shocks and replace them if they're worn out or leaking.

Should I replace shock absorbers in pairs?

Yes, it's generally recommended to replace shocks in pairs (both front or both rear) at the same time. This helps maintain even handling and ride characteristics on both sides of the truck, since one worn shock paired with a new one can cause uneven damping and an inconsistent ride.

What's involved in installing a replacement shock absorber?

Installation typically involves removing the mounting bolts at the top and bottom of the old shock, taking out any worn bushings or sleeves, and installing the new shock with fresh hardware if needed. Torque specs should be followed per your truck's service manual to ensure the shock is properly secured and functions as intended.

Are aftermarket shock absorbers as reliable as OEM parts?

Quality aftermarket shocks are built to match OEM specifications for length, travel, and mounting configuration, and many drivers use them successfully as a cost-effective alternative. That said, it's important to buy from a reputable supplier and confirm the part is designed for your specific Century 112/120 application to avoid fit or performance issues.
