4032FORD SMALL BLOCK 4.030 BORE0.927 PINFLATTOP1.165 CD8 CYL.PISTON SET/8

The SRP Professional Pistons 271097 are advanced lightweight FSR (Forged Side Relief) pistons designed for Ford Small Block engines, specifically the 302 Windsor series. These pistons feature a 4.030-inch bore and are up to 20% lighter than traditional pistons, contributing to improved engine response and performance. They are crafted from high-silicon 4032 aluminum alloy, which allows for reduced piston-to-wall clearance and promotes quieter engine operation.

Key features include accumulator grooves to enhance the piston ring seal, ensuring optimal combustion efficiency. The pistons are equipped with a high-performance skirt coating to minimize friction and wear. They come with a sophisticated low-drag performance piston ring set, consisting of a 1.2mm Carbon Steel top ring, a 1.5mm Napier 2nd ring for superior oil control, and a 3.0mm standard tension oil ring.

Each piston assembly includes high-quality 2.250-inch wrist pins, carbon steel wire locks, and oil rail supports for a complete installation. These pistons are engineered for versatility, making them suitable for naturally aspirated, moderate forced induction, and nitrous oxide applications. Installation typically requires minimal filing for a precise fit.
