4032CHEVROLET LS GEN III/IV 4.005 BORE0.927 PININV.DOME/DISH1.115 CDPISTON KIT

The SRP Professional Pistons 271100 are a set of eight forged pistons for Chevrolet LS2, LS3, LS6, and L92 engines. They feature a 4.005" bore, 4.000" crankshaft stroke, and 6.125" rod length, with a -10cc dish type. Made from high-silicon 4032 forged aluminum alloy, they are up to 20% lighter than traditional equivalents, reducing piston-to-wall clearance and promoting quieter operation. Features include accumulator grooves for improved ring seal, a high-performance skirt coating, and a low-drag performance piston ring package (1.2mm top, 1.5mm Napier 2nd, 3.0mm standard tension oil). They come with high-quality .927" diameter, 2.250" length wrist pins and carbon steel wire locks.
