Description

Manley specializes in engine performance for everything from street to track to drag strip. Their product line-up includes valve train components, pistons, rings, connecting rods, and crank shafts for everything from late model V8’s to sport compacts. 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.
