HKS 2103-RN020 Forged Piston and Connecting Rod Kit

The HKS 2103-RN020 is a high-performance forged piston and connecting rod kit engineered for serious engine builds. This comprehensive Step 2 kit is a JDM Special Order product designed to deliver exceptional strength and reliability under high-stress conditions.

Forged Piston Kit Includes:

• Forged aluminum pistons with nickel-plated surfaces and top ring lands for superior resistance to abnormal combustion and detonation damage
• Complete piston ring sets precision-matched to each piston
• Wrist pins and retaining clips for secure installation
• Available in standard cylinder bore size as well as factory-recommended over-bore sizes

HKS Connecting Rods:

• Engineered and matched specifically to work with HKS piston kits
• Designed to maximize throttle response and power output
• Constructed to handle increased cylinder pressures and RPM

HKS forged pistons feature advanced metallurgy and surface treatments that provide exceptional durability in high-boost and high-RPM applications. The nickel plating on critical surfaces helps prevent piston damage from pre-ignition and detonation, while the forged construction offers superior strength compared to cast pistons. When combined with the matched connecting rods, this kit provides a complete bottom-end solution for builders seeking maximum performance and reliability.
