Nitto Billet Stroker Crankshaft Mitsubishi 4B11T Lancer Evolution X (CZ4A) / Lancer Ralliart (CJ)

Nitto Billet Stroker Crankshaft - Mitsubishi 4B11T - Lancer Evolution X (CZ4A) / Lancer Ralliart (CJ)

This Nitto 4340 billet crankshaft lengthens the stroke of the Mitsubishi 4B11T to 93 mm, taking the Lancer Evolution X or Ralliart engine to 2.2L. It suits circuit and street builds that want more capacity and torque without losing the engine's ability to rev.

It is made in a single 93 mm stroke and pairs with Nitto's 4B11 2.2L stroker pistons and 143.75 mm connecting rods.

Nitto machines the crank from double-melted 4340 true billet bar rather than a forging or lower-grade bar. The design resists flex under load and reduces harmonics compared with factory cranks. A sample of the same material follows each crank through quenching, heat treatment and nitriding, and is then cut up and checked to confirm each process met Nitto's standard.

Note: Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.
