The SDI DU Piston Bushing Conversion Kit is designed to replace the stock wear band in compatible suspension applications. Its bushing conversion design is intended to lower friction and help maintain consistent damping throughout the life of the oil.
Unlike standard piston rings, which can wear significantly during the first five hours and change low-speed damping, this SDI kit is designed to provide more consistent performance over time. The kit has a 46 mm size and manufacturer part number DRPBK-WP46XPL.
Vehicle fitment includes the 2019 KTM 500 EXC-F, 2019 KTM 350 EXC-F, 2020 KTM 300 XC-W, 2021 KTM 250 XC-W, 2025 KTM 250 XC-W, 2025 KTM 500 EXC-F, 2026 KTM 350 EXC-F, 2019 KTM 250 XC-W, 2025 KTM 150 XC-W, and 2024 KTM 350 EXC-F. Distributor part number: 04500619. Verify vehicle application before ordering.
