HKS STEP2 Forged Piston Kit 86.5mm, Ultra Light Double-Layer Coated RB26DETT 21003-AN013

Introducing the HKS STEP2 Forged Piston Kit, a high-performance upgrade for RB26DETT engines. At Terra Firma, we offer this premium piston kit that combines superior quality and optimized design for maximum performance.

Crafted from high heat-resistant A2628 alloy, these 86.5mm pistons are built to withstand the demanding conditions of high-performance engines. The optimized profile features a shorter skirt height and narrow skirt width, reducing weight and improving overall engine responsiveness.

Precision machining techniques are employed to reduce excess thickness, resulting in an ultra-lightweight design that enhances engine efficiency and performance. To further minimize friction, the pistons are coated with a double-layer moly and PTFE coating, reducing friction and promoting smooth operation.

Innovative engineering techniques have allowed for the reduction of axial load by offsetting the piston pin, resulting in improved piston stability and reduced wear. With a weight of 325g, these pistons are significantly lighter than the stock counterparts, further enhancing engine responsiveness and performance.

The HKS STEP2 Forged Piston Kit is designed to withstand high RPMs, with a maximum recommended RPM of 7600rpm. When used in conjunction with the 22001-AN001 Valve Spring and Step2 Camshafts, the RPM can be increased to 8000rpm, unlocking even greater performance potential.

Please note that boring and honing of the engine block is required for proper installation. The compression ratio of these pistons is set at 8.5, providing an ideal balance between power and reliability.

Each kit includes a set of six pistons, allowing for a complete upgrade of your RB26DETT engine. Experience the power and performance gains with the HKS STEP2 Forged Piston Kit from Terra Firma.
