SRP Professional pistons are lightweight FSR forgings offering superior strength and are up to 20% lighter than traditional equivalent pistons. They are made from high-silicon 4032 aluminum alloy for reduced piston-to-wall clearance and quiet operation. Features include accumulator grooves for improved ring seal, and they are designed for normally aspirated or moderate forced induction nitrous engine applications. These pistons come standard with high-performance skirt coating and low drag performance piston rings. They are designed to fit Edelbrock performer & RPM series heads (110 & 112cc) as well as most open chamber GM, Dart, and Brodix Heads. They feature CNC machined domes with radiused valve reliefs for optimum flame travel, and include pin fitting and double spiro locks, as well as wrist pins.
