Malossi set consisting of Delta clutch and clutch bell. More or less the sturdiest clutch that the high-end clutch market has to offer. This premium clutch is highly adjustable- many snap-in points allow the different spring pre-tension settings to be dialed in. If you`re noticing heavy jerking when setting off, or the clutch bell has blued, we recommend swapping out the clutch bell. The clutch is likely to be worn out too. Ignoring this problem will only cause more harm to the drive train and transmission. Malossi is offering here a very well made clutch unit for all normal and tuned engines at an unrivalled low price for the set.
