Forged from high-strength aluminum alloy, this HKS Ni Piston Kit is built to handle the demands of a high-performance engine. The 85.5mm bore size is a specific measurement that matters when you're looking to achieve a particular displacement or compression ratio for your build.

HKS has a long history in motorsport, and this piston kit reflects that experience. The Ni designation often refers to specific material treatments or coatings that HKS applies to enhance durability and reduce friction under extreme conditions. This attention to detail in material science is crucial for components that experience high temperatures and pressures. When rebuilding or significantly upgrading your engine, choosing pistons that are well-made and designed for the stresses involved is paramount. This kit is a solid option for those undertaking a serious engine build where reliability and performance are key.

It's important to note that this kit is not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified mechanic to ensure this piston kit is the right choice for your specific application and to understand any other components you might need for a complete engine rebuild.
