What is a stroker kit and why would I need one?

A stroker kit increases an engine's displacement by using a crankshaft with a longer stroke. This generally leads to more torque and horsepower. You'd need one if you're looking to significantly boost your engine's power output beyond what bolt-on modifications can achieve.

What specific components are included in this HKS stroker kit?

This HKS kit includes a forged crankshaft, forged pistons, and I-beam connecting rods. These are the core components of the rotating assembly needed to increase engine displacement.

What other parts might I need to complete this engine build?

Beyond the stroker kit, you will likely need to consider upgraded engine bearings, gaskets, seals, an oil pump, a performance engine management system for tuning, and potentially an upgraded fuel system to support the increased power potential.

Product Details

This HKS stroker kit is built for the 2008-2010 Mitsubishi Lancer Evolution X, specifically for the 4B11 engine. If you're looking to significantly increase the displacement and potential power output of your EVO X's engine, this kit is a solid foundation. It includes all the essential rotating assembly components needed to transform your stock 4B11 into a larger displacement powerhouse, ready for more aggressive tuning and higher performance goals.

At the heart of this kit is a fully forged crankshaft designed to increase engine displacement. Paired with this are HKS's own I-beam connecting rods, known for their strength and reliability under high stress. The kit also comes complete with a set of forged pistons, which are lighter and stronger than cast pistons, allowing for higher compression ratios and improved durability. These components are all precision-matched to work together, ensuring a well-balanced rotating assembly that can handle the demands of a performance-built engine. This is a comprehensive package for anyone serious about rebuilding or significantly upgrading their EVO X engine.

When undertaking a stroker build like this, it's important to consider that this kit is not CARB approved and cannot be shipped to California. You'll also want to ensure you have all the necessary supporting modifications and tuning in place to take full advantage of the increased displacement and potential power gains. This includes fuel system upgrades, a robust engine management system, and appropriate cooling solutions. This kit is a significant undertaking, but it offers a direct path to a much more potent 4B11 engine.
