High-silicon 4032 aluminum alloy for reduced piston-to-wall clearance and quiet operation. Accumulator grooves for improved ring seal. Designed for normally aspirated or moderate forced induction nitrous engine applications. SRP professional pistons come standard with high-performance skirt coating and low drag performance piston rings.
