HKS STEP2 Forged Piston Kit + Connecting Rods for Nissan GT-R R35

Upgrade your Nissan GT-R R35's engine performance with the HKS STEP2 Forged Piston Kit and Connecting Rods (Part Number: 21003-AN009). This high-performance package is engineered specifically for the VR38DETT engine, designed to handle increased output while maintaining reliability.

Key Features

  • Enhanced Engine Output: Factory replacement pistons and connecting rods with a standard bore size, optimized for superior performance.
  • Durable Forged Construction: Unlike factory cast pistons, HKS uses forged materials to prevent piston land breakage.

  • Tested Reliability: In-house testing at 900PS has confirmed the durability and safety of this setup.

  • Precision Design: The STEP2 piston features a 1mm deeper recess than stock to work seamlessly with the STEP2 camshaft.
  • Weight Consideration: The connecting rods maintain the same weight as factory parts to account for the V6 engine's unique vibrations, while the pistons are lightweight at approximately 25g.
  • Made in Japan: All components are manufactured in Japan, ensuring the highest quality standards.
