HKS FA24 2.5L High Comp Step 1 Piston Full Kit
Piston Kit
- To prevent the breakage of the second land, the material employs A2618 material, which has high-temperature strength, to achieve a low pin height that eliminates the need for making any service holes.
- 2-layer molybdenum coated to help reduce friction.
- The cavity on the piston head optimizes the atomization of direct injection.
- 3D Piston crown shape sustains tumble flow.
- The uneven shape of the piston head allows using the high-lift camshaft.
Connecting Rod
STEP 1
- 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
- Crankshaft uses a forged material.
- It has a dedicated pin journal size. Combination use of the HKS connecting rod is recommended.
What's Included
- Forged piston kit
- I-beam connecting rod
- Forged crankshaft
HKS recommends using STEP 2 for a vehicle with a turbo that tends to be generated high torque.
