HKS Step2 Forged Piston Kit For RB26 - 86.5mm Bore

21003-AN013

The HKS Stage 2 Piston Kit for the RB26DETT features an ultra-lightweight forged piston, that despite an 86.5mm bore, reduces rotating mass weight and increases efficiency. The HKS Forged Piston kit is a low friction, double-layer coated OEM replacement piston kit redesigned to achieve lighter weight and durability. An ideal upgrade to the OEM pistons during an overhaul, this forged piston is also fully compatible and truly performs when paired with the HKS Stage 2 Camshaft kit. 

Features:

• High strength, ultra-lightweight, and low friction
• Adapting truss structure for improved structural rigidity
• Made of highly heat resistant and durable A2628 alloy
• Weight - Piston: 352g
• Optimized profile for shorter skirt height and narrower skirt width
• Machine to reduce excess thickness, reducing weight
• Double-layer moly and PTFE coating to reduce friction
