EBC is a company that does not replicate a clutch kit, they make it better, and that is exactly what they have done with the DRC Dirt Racer Clutch Kit. The EBC Clutch Kit fiber plates have been impregnated with aluminum particles that reduce swelling, provide heat resistance and make for a longer lasting clutch kit. The fiber plates in the EBC Dirt Racer clutch kit have modified flanges that reduce "dogging" from the clutch basket. To further improve clutch kit performance, EBC stiffened the clutch springs by 15%. Stiffer clutch kit springs ensure better contact between the clutch plates to reduce wear. The EBC DRC Dirt Racer Clutch Kit was designed as a direct O.E.M. replacement. Notes: Soak friction plates in drive-case oil for a few hours before install. NOT for use with 100% synthetic oil.
