Description

These “Pro Series” 4340 alloy steel crankshafts are available with many value packed and high-performance enhancing features.

  • Lightweight Design: Manufactured from a premium 4340 steel forging, gun drilled mains and lightened rod journals contribute to weight reduction and optimize engine performance. Counterweights are fully profiled to ensure precise balance and stability.
  • Enhanced Strength: A multi-step heat treatment process and nitriding enhance the crankshafts’ strength and longevity.
  • Micro-Polished Journals: Large radius journals are micro-polished to reduce friction and enhance performance.
  • Rigorous Quality Assurance: Each crankshaft undergoes stress relief, shot peening, and 100% magnafluxing to meet our stringent quality standards.
  • Increase Displacement with a “Stroker” Crankshaft: These crankshafts feature a 4.050” stroke which can turn your 5.7L into a 392 c.i. engine and your 6.1L/6.4L into a 426 c.i. engine.

Note: Manley crankshafts are not intended for use with highly boosted roots style cog belt superchargers.

A heavier target Bobweight will allow you to more accurately balance the rotating assembly instead of adding weight to a lighter crankshaft. 1700, 1730 and 1770 weights are available.
