If your Freightliner SD 108 or 122 rides rough, bounces over bumps, or feels loose under load, it might be time for new shocks. Replacing them helps restore a smoother ride, better handling, and more control on the road.

Freightliner SD 108/122 Shocks & Replacement Components

Aftermarket Freightliner SD 108 and 122 shocks are built for heavy-duty reliability. They absorb road impact, reduce vibration, and help your suspension stay tight and responsive. Whether your truck runs Hendrickson, Meritor, or Gabriel systems, you'll find replacement options that fit right and last long. Each shock features durable construction and double-lip seals for consistent, leak-free performance. When you install new shocks, it's smart to inspect your bushings, bolt kits, and mounts as well. We carry an array of shock dampener and suspension-related hardware component to help with that. - Bushings absorb vibration and prevent metal-on-metal wear. - Bolt kits and spacers maintain alignment and secure fitment. - Upper mounts and studs stop rattling and looseness under load. If you notice uneven tire wear, excessive bounce, or vibration in the cab, your suspension may be due for attention. Keep your truck smooth, steady, and comfortable with additional performance upgrades like Freightliner SD 108/122 front axle air ride kits and Freightliner SD 108/122 level valves built for long miles and tough conditions.
