If your Peterbilt 386 feels rough over bumps or starts to sway more under load, your shocks may be worn out. Replacing them helps bring back stability, comfort, and control, keeping your truck safer and smoother on every run.

Shop Quality Shocks for Better Stability & Handling

Aftermarket heavy-duty truck shocks are built for heavy-duty performance and long service life. They absorb road impact, reduce vibration, and help your suspension stay tight and responsive. Designed to fit multiple Peterbilt models, including the 379, 384, 387, 389, and more, these shocks deliver consistent damping and reliable handling mile after mile. When replacing shocks, it's smart to check your mounting hardware and bushings too: - Bushings isolate vibration and stop metal-to-metal wear. - Bolt kits and spacers keep alignment and fitment secure. - Upper mounts and studs prevent clunks and looseness under load. If you notice bouncing, drifting, or uneven tire wear, your suspension is due for attention. Restore you whole ride by upgrading your Peterbilt 386 air springs, Peterbilt 386 front axle air ride kits and mounting components for better long-haul comfort and control.
