- Description
HKS reinforced pistons and connecting rods have been specifically designed to withstand the high boost and power levels of the S07A engine.
Using A2618 material known for its excellent high-temperature strength enables thinner walls for reduced weight. Precision machining removes excess material, contributing to a lightweight construction.
The bridge design enhances structural rigidity while maintaining weight savings. The piston crown matches the original shape, coated with a dual-layer finish to enhance seizure resistance and reduce friction.
Connecting rods are crafted from chrome steel with an I-beam profile, offering 74% greater strength compared to stock components, and feature WPC surface treatment for improved fatigue resistance.
