The new fortune auto generation 5 internal floating piston is considerably lighter and uses a low-drag teflon band that drastically reduces stiction. This allows the damper to react quicker to shock forces. The fortune auto 500 series damper shaft seals have 40% less drag than our previous models. This provides for less hysteresis and for superior control of driver inputs. Our new seals are made of a specially formulated buna rubber compound that provides a great balance between reliability and performance! Since the shaft seal is the most important seal on the shock, a stronger seal will greatly improve quality and performance.shims are deflection disks that cover up the port holes on a piston. They regulate t...(choose a part on the right to read more)
