SRP Professional pistons are advanced lightweight FSR forgings offering superior strength. They are up to 20% lighter than traditional equivalent pistons. Made from high-silicon 4032 aluminum alloy for reduced piston-to-wall clearance and quiet operation. Features accumulator grooves for improved ring seal and 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. Ring land and crown thickness are specifically engineered for mild turbo, supercharged, and nitrous applications. They also feature CNC machined domes with radiused valve reliefs for optimum flame travel, forced pin oiler for increased wrist pin lubrication, and include pin fitting and double spiro locks.
