This engine upgrade kit is a direct replacement for the core components of your engine, including the crankshaft, pistons, and connecting rods. Designed to maintain the standard piston diameter while increasing the stroke, it boosts displacement to 2498cc without requiring extensive modifications like boring or honing. The upgraded internals are not only stronger and lighter but also engineered for smoother operation with reduced friction. Available in two configurations, the Step 2 version features durable billet-type I-beam connecting rods, making it ideal for high-torque, forced induction setups. This kit provides a rock-solid foundation for further tuning, ensuring maximum performance and reliability.
