Wiseco is the only aftermarket piston manufacturer in the United States that produces pistons exclusively through the forging process. Each piston starts with aerospace-grade aluminum, where the forging process compresses and aligns the material's grain structure for optimal strength, ductility, and durability. The 60004RX130 is built to perform in high-horsepower LS7 race and performance builds where reliability and precision are non-negotiable.
