DETAILS

- Forged crankshaft for strength and reliable increased stroke.

Pistons
Uses high-temperature A2618 material to prevent second land breakage and eliminate the need for service holes. 2-layer molybdenum coating reduces friction. Piston head cavity optimizes direct injection atomization. 3D piston crown shape maintains tumble flow. Uneven piston head shape supports high-lift camshaft use.
Connecting Rod
- Exclusive conrods designed for longer stroke.
- The crank pin size is designed for a dedicated size. Thus it eliminates the modifications on the engine side.
- It optimizes the connecting rod bolt size and employs the high-strength split-type (not machined the cutting surface) I-beam.
Crankshaft
The crankshaft of this product is comprised of a forged material and features a specifically designed pin journal size. For optimal performance, we highly recommend pairing it with the HKS connecting rod.
NOTE: HKS recommends using STEP 2 for a vehicle with a turbo that tends to be generated high torque.
