Wiseco Chevy Small Block 4.135in Bore 1.125in CH -5.00 CC Piston Set

Starting with pistons forged from 2618 aluminum, Wiseco's Professional Series sets are built for the demands of serious racing and heavy-duty performance applications. This set is specifically for Chevrolet Small Block engines with a 4.135-inch bore, featuring a 1.125-inch compression height and a -5.00cc dish volume, which is crucial for achieving your desired compression ratio when rebuilding your top end.

These pistons are fully machined in the USA, including precision ring grooves designed for improved sealing. They also incorporate anti-detonation grooves and other features to enhance ring seal under extreme conditions. The ArmorGlide skirt coating is applied to reduce friction, minimize wear, and help prevent seizure, all while contributing to quieter operation. The crown is also fully machined for accuracy, and the design includes forced pin oiling to ensure the wrist pin receives adequate lubrication.

This set includes eight pistons, ready for your high-performance engine build. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're building a severe-duty race engine, these Wiseco pistons are a solid option to consider for their robust construction and performance-focused features.
