Manley offers crankshaft keys for LS/Hemi applications. These semi-circular shaped removable parts—also called woodruff keys—fit into matching keyways cut into the crankshaft, leaving protruding tabs. These tabs mate with matching slots on the harmonic balancer flush upon the shaft. They are used to improve the concentricity of the shaft and the mating part, which is critical for high-speed operation. Order the key recommended for your year, make, and engine family.

Manley Pro Series crankshafts can make your short block bulletproof. They feature forged 4340 construction and undergo a multi-step heat-treatment process and are then nitrided for added strength. The crankshafts are stress-relieved, shot-peened, and magnafluxed. Manley Pro Series crankshafts have micro-polished large .125 in. radius journals, gun-drilled mains, and lightened rod journals for weight reduction. The counterweights are fully profiled and they are designed for internal balancing.
