PRODUCT DESCRIPTION
The ZRP super-lightweight stroker crankshaft for the Mitsubishi 4G63 is manufactured from exceptionally durable EN40B steel, designed to withstand the most extreme conditions. EN40B is the strongest material available, with superior hardening capacity compared to standard 4340 steel.
This high-quality material allows an engine with an EN40B steel crankshaft to reach higher, smoother RPMs thanks to its unique resonance. By increasing the stroke with a lightweight crankshaft, this stroker crankshaft, weighing only 13.3 kg, is perfect for high-revving engines, taking your 4G63 to a new level.
Increasing the stroke will increase torque and power.
Additionally, the fully counterweighted and precision-balanced crankshaft increases torque and ensures smooth, fluid acceleration. Additional information
