Belltech engineers are dedicated to staying ahead of new technology to provide you with the best suspension options on the market. Our exceptional Street Performance shocks deliver advanced performance and handling you can feel! ?We have engineered a product that will continually deliver the driving experience you seek.? Each shock is made of painted, heavy-duty steel so it will last and not rust over time.? The shock?s 35mm independent rebound and compression valves and low friction design give it flawless damping, and the forces within each damper have been perfectly preset and tuned for your specific vehicle.? Each shock also features a large 2.2" (55mm) body that holds increased amounts of oil.? The purpose behind this is to keep the oil cool and give you outstanding suspension behavior even over long periods of time.? A high durometer vulcanized rubber bushing is used to reduce unwanted noise, friction, and vibrations. To add strength and durability, a 15mm hardened chrome piston rod is applied.? Keeping a shock clean and free of debris is also vital for its lifespan and performance, so a metal dust boot creates a forcefield around the more crucial components.? Create the ultimate driving machine with the help of our advanced Belltech Street Performance shocks.?
