SRP Professional pistons are advanced 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 are 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. 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, forced pin oiler for increased wrist pin lubrication, and include pin fitting and double spiro locks. 927-2750-150 wall wrist pin (130 grams) included. CNC Machined ring grooves accept 1/16, 1/16, 3/16mm rings (Rings Sold Separately).
