JE Pistons Chevrolet Small Block 4.030in Bore 1.425in CH -5.00 CC Piston Kit

SRP Professional pistons are the most advanced lightweight FSR forging, offering superior strength and up to 20% lighter than traditional equivalent pistons. Made from high-silicon 4032 aluminum alloy, they ensure reduced piston-to-wall clearance and quiet operation. Designed for normally aspirated or moderate forced induction/nitrous applications, they feature a high-performance skirt coating, low drag rings, forced pin oilers, and include pin fitting and double spiro locks. These pistons are for Chevrolet Small Block (SBC) engines with a 4.030-inch bore, 3.750-inch crankshaft stroke, and 5.700-inch connecting rod length.
