Wiseco Chevy LS 4.035in Bore 1.165in CH 5.00 CC Piston Set

Starting with a 2618 aluminum forging, these Wiseco pistons are machined in the USA for your Chevy LS engine. This material choice is key because it offers improved tensile strength, which is crucial when you're pushing your engine hard. The 4.035-inch bore size is a common specification for many LS engine builds, and the 1.165-inch compression height works with a variety of crankshafts and connecting rods.

Wiseco has packed these pistons with features for serious builders. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The crown is fully machined for accuracy, and they even include forced pin oiling to keep the wrist pins well-lubricated under high stress. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also resisting seizure. These are built to handle heavy to severe duty performance applications, so you can remove your limits.

This set includes eight pistons, along with the necessary wrist pins and locks. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
