If your Peterbilt 388 rides rough, leans in turns, or feels unstable on uneven roads, your shocks may be worn out. Replacing them helps restore stability, comfort, and control, especially when you're running heavy loads or long routes.

Find Top-Performing Shock Brands for Your Pete 388

Aftermarket Peterbilt 388 shocks are built for tough, commercial use. They absorb impact, cut vibration, and keep your truck steady mile after mile. Choose from heavy-duty options that match your setup, including Hendrickson Turner, Gabriel Fleetline, and Monroe 65 Series replacements. Each is designed for durability, proper fitment, and consistent performance under load. When you install new shocks, inspect your mounting hardware and bushings too: - Bushings reduce vibration and prevent metal-on-metal contact. - Bolt kits and spacers keep the shocks tight and properly aligned. - Upper mounts and studs stop rattles and clunking under load. If you notice extra bounce, uneven tire wear, or steering looseness, it's time to refresh your suspension. Pair your replacement shocks with additional driving and handling upgrades, likePeterbilt 388 air ride kits, Peterbilt 388 air springs and various mounting components designed for stable, smooth driving.
