4032CHEVROLET SMALL BLOCK 4.155 BORE0.927 PININV.DOME/DISH1.260 CDPISTON SET/8

SRP Professional pistons are advanced, lightweight FSR forgings, offering superior strength and up to 20% lighter than traditional equivalent pistons. Crafted from high-silicon 4032 aluminum alloy, they allow for reduced piston-to-wall clearance and quieter engine operation. Features include accumulator grooves for improved ring seal and suitability for normally aspirated, moderate forced induction, and nitrous engine applications. Standard with high-performance skirt coating and low-drag piston rings, their ring land and crown thickness are engineered for mild turbo, supercharged, and nitrous setups. Each piston has CNC machined domes with radiused valve reliefs for optimal flame travel. The kit includes forced pin oilers for increased wrist pin lubrication, along with pin fitting and double spiro locks. Optional bearing steel pins are available.
