Crank Toyota 2JZ 86mm Stroke 4340 Billet

The DART Crank Toyota 2JZ 86mm Stroke 4340 Billet crankshaft is a precision-engineered rotating assembly component designed for high-performance 2JZ engine builds. Built from 4340 billet steel and featuring internal balance geometry, this crankshaft delivers the reliability and strength required for forced-induction and high-RPM applications where factory components fall short.

The 86mm stroke dimension is critical for engine displacement calculations and bottom-end harmonics. As a one-piece seal design, this crankshaft reduces leak points common in multi-piece configurations and simplifies installation during engine assembly. The 4340 billet steel construction provides superior material homogeneity compared to cast alternatives, offering greater fatigue resistance under sustained high-boost conditions and extended track use. Weighing 64.3 lbs, it maintains the mass characteristics required for proper engine balance when paired with matched pistons and connecting rods. This component is fully compatible with Toyota JZ-Series engine platforms, including the 2JZ-GE and 2JZ-GTE variants.

Engine builders, performance shops, and serious enthusiasts tackling 2JZ turbo conversions, naturally-aspirated builds, or long-block restoration projects rely on OEM-specification crankshafts when pushing displacement or RPM limits. This DART unit fills that demand with verified 4340 billet construction and internal balancing, eliminating the guesswork in sourcing critical rotating assembly components. Whether sourcing parts for a track car, daily-driven modified platform, or engine swap project, proper crankshaft selection directly impacts reliability and service life.
