HKS 23004-AN006 Piston and Connecting Rod Kit with H-Beam Con Rods

The HKS 23004-AN006 Piston and Connecting Rod Kit is a complete performance engine internals solution engineered for high-output and modified engines. This kit pairs HKS forged aluminum pistons with precision-matched H-Beam connecting rods to deliver improved power response, durability, and reliability under demanding performance conditions.

HKS Forged Aluminum Pistons:

• Complete piston sets including piston rings, wrist pins, and retaining clips
• Available in standard cylinder bore size as well as factory-recommended over-bore sizes
• Nickel-plated surfaces and top ring lands for exceptional resistance to damage caused by abnormal combustion (detonation/pre-ignition)
• Forged aluminum construction for superior strength-to-weight ratio compared to cast pistons

HKS H-Beam Connecting Rods:

• Designed and matched specifically to HKS piston kits for optimal fitment and balance
• H-Beam design provides excellent rigidity and resistance to bending loads at high RPM
• Engineered to improve throttle response and maximize power output
• Built to withstand the stresses of forced induction and high-performance engine builds

This kit is ideal for performance engine rebuilds where stock internals are insufficient. The combination of HKS forged pistons and H-Beam connecting rods ensures a matched, balanced assembly straight from the manufacturer, reducing build complexity and improving long-term reliability.
