BC5457 - Chevrolet LS Series Crankshaft - 4340 Forging - 4.100 Stroke, Fully Balanced w/58 Tooth Wheel

This 4340 forged crankshaft is fully balanced for top - notch performance. Each crank undergoes stress relief, shot peening, magna flux inspection, and nitriding (a multi - step heat treatment). The fully profiled counterweights reduce windage in the crankcase, minimizing oil resistance and enhancing rpm potential. Specifications include a 4.100' stroke, 2.0987' rod journal, and 2.558' main journal.

To use this crankshaft, first make sure it's installed correctly in your Chevrolet LS Series engine following the engine's manual. When installing, handle it gently to avoid any damage. During operation, keep an eye on the engine's performance and oil pressure. For maintenance, regularly check the crankshaft for any signs of wear or damage. If you notice any abnormal noises or vibrations, stop using the engine immediately and have the crankshaft inspected. Periodically change the engine oil to keep the crankshaft lubricated properly and extend its lifespan.
