Wiseco Chevy LT1 Gen V 4.125in Bore 1.105in CH -20cc Dish Piston Kit

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance builds. The 4.125-inch bore size is specific to certain Chevrolet LT1 Gen V engines, and the 1.105-inch compression height is a key measurement for achieving the correct deck height and piston-to-head clearance in your build. Each piston features a -20cc dish, which is important for setting your desired compression ratio when paired with specific cylinder heads.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal enhancements to ensure reliable performance under extreme conditions. The crown is fully machined for accuracy, and forced pin oiling helps keep the wrist pin lubricated. They also come with an ArmorGlide skirt coating, which is designed to reduce friction, resist seizure, and operate more quietly.

This kit includes a set of 8 pistons, along with premium rings, ready for installation in your LT1 Gen V engine. Remember that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or service manual for specific installation procedures and compatibility with other engine components.
