Manley Performance Forged Crankshaft 4340 Non-Twist Lightweight Design

Manley Performance Forged Crankshaft — 4340 Non-Twist Lightweight Design Elevate engine response and reliability with the Manley Performance Forged Crankshaft. Engineered from 4340 non-twist forging, this lightweight crankshaft delivers superior strength, reduced rotational mass, and precise balance for high-performance applications. 4340 Non-Twist Forging: High-grade alloy steel forging resists distortion under extreme loads for consistent geometry and long life. Lightweight, Optimized Design: Gun-drilled mains and lightened rod journals reduce reciprocating mass to improve throttle response and rev capability. Fully Profiled Counterweights: Precisely profiled counterweights ensure stable balancing and minimize vibration at high RPM. Enhanced Surface Strength: Multi-step heat treatment and nitriding provide exceptional fatigue resistance and wear protection. Micro-Polished Journals: Large-radius, micro-polished journals reduce friction for smoother operation and improved bearing life. Rigorous Quality Assurance: Each crankshaft is stress relieved, shot peened, and 100% magnaflux inspected to meet demanding performance standards. This Manley crankshaft is ideal for builders seeking a race-ready, durable rotating assembly that maximizes power delivery while maintaining reliability. Backed by precision manufacturing and comprehensive inspection, it’s a trusted upgrade for forced-induction and high-RPM engines.
