SRP Professional pistons are advanced lightweight FSR forged pistons (up to 20% lighter than traditional equivalents). They are made from high-silicon 4032 aluminum alloy for reduced piston-to-wall clearance and quiet operation. They feature accumulator grooves for improved ring seal and are suitable for naturally aspirated, moderate forced induction, and nitrous applications. They come standard with high-performance skirt coating and low drag performance piston rings. The ring land and crown thickness are specifically engineered for mild turbo, supercharged, and nitrous applications. They have CNC machined domes with radiused valve reliefs for optimum flame travel. Optional bearing steel pins are available. Forced pin oiler for increased wrist pin lubrication. Pin fitting and double spiro locks are included. They include a 927-2750-150 wall wrist pin (130 grams). CNC machined ring grooves accept 1/16, 1/16, 3/16mm rings (rings sold separately).
