Tusk Clutch Cover Gasket
Dan in MO
Perfect fit
Fit perfectly and stopped my leak. Simple things that work like they're supposed to make me happy. Tusk is my go-to for value.

I am very pleased with this kit and the quality.
The clutch kit is exactly what they claim. Very good quality and fitment. I would purchase another kit when the time comes.

EBC Clutch Spring Set
Marcus in UT
Great Springs!
EBC is always a reliable go to. Swapped out some old springs with these and I'm happy how they worked out. Little stiffer than stock but not bad at all (probably need to lube my cable as well) plus they hook up nicely when riding more aggressively. Great springs!
