4032FORD SMALL BLOCK 4.040 BORE0.912 PINDOME1.540 CDPISTON SET/8

SRP Professional pistons are advanced lightweight FSR forgings designed for superior strength. They are up to 20% lighter than traditional equivalent pistons, crafted from high-silicon 4032 aluminum alloy for reduced piston-to-wall clearance and quiet operation. Key features include accumulator grooves for improved ring seal, making them suitable for normally aspirated or moderate forced induction/nitrous engine applications. These pistons come standard with a high-performance skirt coating and low-drag performance piston rings. They are ideal for high-performance street/strip or vintage road racing. The solid dome with a special profile is designed to fit small chamber Australian 302 2V heads and can also be milled flat for use with various aftermarket heads. They incorporate forced pin oilers for enhanced wrist pin lubrication and CNC machined ring grooves that accommodate 1/16, 1/16, 3/16 rings (sold separately). Each kit includes a .912 x 2.750 x .140 straight wall wrist pin, weighing 123 grams.
