HKS Forged Piston Kit RB26 2-Step 87mm

Forged from high-strength aluminum alloy, this HKS piston kit is built to handle the demands of a performance-tuned RB26 engine. The 87mm bore size is a common upgrade for those looking to increase displacement and power output from their RB26 powerplant. These pistons feature a specific dish design, often referred to as '2-Step', which is engineered to optimize combustion chamber volume and compression ratio for specific engine builds, especially those aiming for high boost pressures or specific ignition timing strategies.

HKS has a long history of developing parts for performance Japanese engines, and this piston set reflects that experience. The forged construction offers significantly improved strength and durability compared to cast pistons, making them a solid choice for engines that will see hard use or significant modifications. The kit includes all the necessary pistons for a complete engine rebuild, ensuring you have matched components for balanced performance. Proper installation by a qualified mechanic is recommended, as piston replacement is a critical engine internal job.

When rebuilding or significantly modifying your RB26 engine, choosing reliable internal components is key. This HKS forged piston kit offers a well-built solution for enthusiasts looking to push the performance envelope. Remember that this kit is not CARB approved and cannot be shipped to California. Always consult your engine builder or a professional mechanic to ensure this kit is the right choice for your specific build goals and to follow the correct installation procedures.
