BBC Flat Top Piston Set 4.500 Bore -3cc

SRP Professional pistons are advanced lightweight FSR forged pistons offering superior strength and up to 20% lighter than traditional equivalents. Made from high-silicon 4032 aluminum alloy for reduced piston-to-wall clearance and quiet operation. Features include accumulator grooves for improved ring seal, engineered for normally aspirated or moderate forced induction/nitrous engine applications. They 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. Includes forced pin oiler for increased wrist pin lubrication, CNC machined domes with radiused valve reliefs for optimum flame travel, pin fitting, and double spiro locks (#990-042-CS). Also includes 990-2930-15-51S wrist pins (150 grams). CNC machined ring grooves accept 1/16, 1/16, 3/16mm rings (Rings Sold Separately).
