Street Hyper Piston Set
Upgrade your early-block Toyota engine with our Street Hypereutectic Piston Set. Engineered for high-performance street builds, daily drivers, and mild off-road setups, these pistons offer superior strength, thermal efficiency, and durability compared to standard cast pistons.
Crafted from a high-silicon aluminum alloy, these hypereutectic pistons feature minimal thermal expansion. This allows for tighter piston-to-wall clearances, resulting in quieter operation, better oil control, and reduced blow-by.
Features & Benefits
- High-Silicon Hypereutectic Alloy: Delivers excellent heat resistance and strength, easily handling the increased cylinder pressures of high performance street builds.
- Tighter Clearances: Low thermal expansion properties allow for precise fitment, ensuring a quieter engine at startup and improved ring seal.
- Precision Machined: Features weight-matched piston crowns and optimized skirt profiles to reduce friction and maximize engine life.
Kit Includes
- 4x Hypereutectic Pistons
