Malossi set consisting of Delta Clutch clutch and bell. Pretty much the most robust clutch on the market in the field of high-end clutches. These top clutches provide many levels of adjustment. Various nothces are provided for different spring preloads. If a strong jerking is noticed under load, or the clutch bell is blued, we recommend replacing the clutch bell. In this case, the clutch is probably already worn. Ignoring this problem will cause further damage to the drive train and the gearbox. Malossi offers a very well-made clutch unit for all normal and tuned engines at an unrivaled price.
