SDI DU Piston Bushing Conversion Kit - 40 mm DRPBK-KYB40
Part Number: 04500623Description
Stock piston rings wear rapidly during initial operation, compromising your damper's low-speed performance within just five hours of use. The SDI DU Piston Bushing Conversion Kit replaces that stock wear band with a precision-engineered bushing that maintains consistent damping characteristics throughout the service life of your oil. By significantly reducing friction at the piston seal, this kit preserves the tuning intent of your suspension setup and eliminates the performance drift caused by traditional ring degradation.
