4032CHEVROLET SMALL BLOCK 4.040 BORE0.927 PINDOME1.125 CDPISTON SET/8

SRP Professional pistons are forged from 4032 aluminum, offering minimal thermal expansion for high-performance daily driver or street/strip applications. They feature an advanced lightweight FSR forging, making them up to 20% lighter than traditional equivalent pistons. Designed for normally aspirated or moderate forced induction/nitrous engine applications, they include high-silicon 4032 aluminum alloy for reduced piston-to-wall clearance, quiet operation, and accumulator grooves for improved ring seal. Each piston comes standard with a high-performance skirt coating, low drag performance piston rings, premium ring sets, wrist pins, and locks. JE Pistons are designed, forged, and machined in-house, leveraging 7+ decades of racing experience to offer features like full billet construction, EN plating, and purpose-designed coatings.
