Clutch Masters 850 Series 8.5in twin‑disc clutch kit uses a billet aluminum cover that is Type‑3 hard anodized to increase tensile strength and reduce flex compared with cast units. Reduced cover flex improves clutch consistency and clamping force; the kit’s QR Quick Release system helps smooth engagement and cut noise. This conversion kit requires a Clutch Masters flywheel and will not work with an OEM flywheel.
