190100

Manley Performance crankshafts are designed with the highest standards in mind. Each crankshaft is put through a multi-step heat treatment process and nitrided (hardened) for maximum strength. The crankshaft is then stress relieved, shot peened, and magnafluxed (stress tested). The center, crank pin and counterweights are gun drilled for reduced weight.

Race Series forged crankshafts are a major improvement over the OEM piece and feature special teardrop, diagonal oiling features not found on stock OEM style cranks.

This Steet / Stip crankshaft features an 88mm stroke and weighs 33.5 pounds.
