SDI DU Piston Bushing Conversion Kit - 40 mm DRPBK-SH40
Part Number: 04500616Description
Stock piston rings are a compromise between cost and performance—they wear rapidly during initial operation, causing your damping characteristics to shift unpredictably within the first five hours. The SDI DU Piston Bushing Conversion Kit replaces that wear band with a proven DU bushing material that maintains consistent low-speed damping throughout the life of your oil, eliminating the guesswork and delivering stable suspension behavior lap after lap. If you're serious about tuning and repeatability, this is the upgrade that actually delivers measurable results.
