Belltech Street Performance OEM Shock Absorber

The Belltech Street Performance shock absorber features a large 45mm body diameter and a twin-tube design, which allows for more oil volume and better heat dissipation. This helps keep the shock working effectively for longer, especially under demanding conditions. The engineers focused on tuning the low-speed compression characteristics, which is key to controlling your Expedition's pitch, roll, dive, and squat. This means a more stable and confident feel when you're driving, whether you're navigating everyday roads or carrying a load.

Inside, you'll find a 35mm piston and valves designed for greater hydraulic control during quick wheel movements and over the full range of the shock's travel. A low-friction sealing and guide system ensures the damper reacts quickly to even small motions without significant temperature increases. The hardened chrome 15mm piston rod is protected by a steel dust cover that won't degrade from UV exposure or chemicals, and a triple-lip NBR rod seal helps keep contaminants out. For a smoother ride, the shock uses high-durometer vulcanized rubber bushings that help reduce noise, vibration, and harshness.
