CHEVROLET SMALL BLOCK 4.020 BORE0.927 PINDOME1.125 CDPISTON SET/8

SRP Professional pistons are advanced lightweight FSR forgings offering superior strength, up to 20% lighter than traditional equivalent pistons. Made from high-silicon 2618 aluminum alloy, they allow for reduced piston-to-wall clearance and quiet operation. They feature 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. They are designed for use with the most popular 23° heads and have CNC machined domes with radiused valve reliefs for optimum flame travel. Pin fitting and double spiro locks are included, along with 927-2750-150 wall wrist pins (130 grams). CNC machined ring grooves accept 1/16, 1/16, 3/16mm rings (rings sold separately). Oil rail supports are also included. Ideal for oval track to street/strip applications.
