Wiseco Chevy LS 4.065in Bore 1.165in CH -9.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious racers and builders who need a strong, reliable component for their Chevy LS engine. The 4.065-inch bore size is a common upgrade for LS engines looking to increase displacement, and the 1.165-inch compression height is specifically designed to work with many popular LS crankshafts and connecting rods to achieve the desired -9.00cc piston dish volume, which helps achieve a specific compression ratio.

Wiseco machines these pistons right here in the USA, focusing on precision in every detail. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal and prevent detonation, which is crucial when you're pushing an engine hard. The ArmorGlide skirt coating isn't just for show; it helps reduce friction, making the engine run a little smoother and quieter, while also resisting seizure. The fully machined crown ensures a clean combustion chamber surface, and forced pin oiling helps keep the wrist pin lubricated under extreme conditions.

This set includes eight pistons, along with premium rings, ready for a heavy-duty or severe-duty performance build. Keep in mind these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and durability in their LS engine, these Wiseco pistons are a solid choice.
