Wiseco Chevy LS 4.065in 1.165in CH -17.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty LS engine builds. The 4.065-inch bore size and -17.00cc dish volume are specific dimensions for certain LS engine configurations, and the 1.165-inch compression height is crucial for achieving the correct deck height and piston-to-valve clearance in your build. These aren't just off-the-shelf parts; they're crafted with precision for performance applications where reliability under extreme stress is paramount.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal enhancements to ensure optimal combustion control and durability. The ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, which is vital when pushing an engine hard. Forced pin oiling is also included to keep the wrist pin properly lubricated under high loads. The fully machined crown ensures consistent performance across all eight cylinders.

This set includes eight pistons, designed to withstand severe duty performance applications. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
