EBC Clutch Kit
★★★★★
Christopher in SD
Great quality and budget friendly clutch kit.
Smooth clutch kit only thing it's missing and I highly recommend you getting is replacement clutch spring bolts, I wasn't thinking that far ahead when I did mine the first time and one of the old spring bolts broke off in my basket and I had to replace the bolts and basket.
