937977 Steel drive plate, clutch

Keeping a vintage 45 inch Sidevalve on the road requires the right internal components, and this steel clutch drive plate from MCS is a perfect example. Designed to fit 1941 to 1973 45 inch SV models, this plate is a faithful reproduction of OEM 37977-41. Over time, these steel plates can warp or develop heat spots, leading to clutch slip and inconsistent lever feel. Replacing them during a primary service is a straightforward way to ensure your flathead's power is getting to the ground efficiently. Whether you are doing a full restoration or just routine maintenance, this plate offers the durability and fitment required for these legendary Harley-Davidson powerplants.
