Wiseco Chevy LS 4.065in Bore 1.300in CH -11.00 CC Piston Set

If you're building a high-performance Chevrolet LS engine for serious racing or heavy-duty applications, a strong set of pistons is crucial. This Wiseco Professional Series piston set is designed to handle the extreme demands of competition. Each piston is forged from 2618 aluminum right here in the USA, giving it improved tensile strength to resist deformation under high cylinder pressures.

Wiseco has packed these pistons with features that matter for racing. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal, which is key for both power and engine longevity. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and even makes operation quieter. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins lubricated under extreme conditions. These are built to withstand heavy to severe duty performance builds, removing limits for serious racers.

This set includes eight pistons, each designed for a 4.065-inch bore with a 1.300-inch compression height and a 0.927-inch pin diameter. 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.
