SDI DU Piston Bushing Conversion Kit - 50 mm DRPBK-SH50
Part Number: 04500617Description
Stock piston rings shed their wear band rapidly, often within the first five hours of operation, causing unpredictable low-speed damping and performance loss. The SDI DU Piston Bushing Conversion Kit eliminates this inconsistency by replacing that wear band with a DU bushing material engineered to maintain stable damping characteristics throughout the life of your oil. This conversion delivers the precision and reliability professional racers demand—consistent performance from lap one through the season.
