Wiseco Chevy LS 4.010in Bore 1.165in CH -9.00 CC Piston Set

Wiseco's Professional Series forged pistons are built for serious Chevy LS engine builders tackling heavy to severe duty race applications. These pistons start as 2618 aluminum forgings, chosen for their improved tensile strength, and are then machined right here in the USA. The precision machining includes the ring grooves, anti-detonation grooves, and features designed for additional ring seal, all contributing to better performance and durability under extreme conditions.

You'll also find an ArmorGlide skirt coating on these pistons. This isn't just for looks; it helps reduce friction, resist seizure, and makes for quieter operation. The fully machined crown and forced pin oiling are further details that show these pistons are designed to handle the demands of racing. This set is for an 8-cylinder engine, with a 4.010 inch bore, a 1.165 inch compression height, and a -9.00cc dish volume, which will affect your compression ratio.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance LS engine for racing, these Wiseco pistons are a solid option to consider for their robust construction and race-focused features.
