Wiseco Chevy LS 4.185in Bore 1.165in CH -23.00 CC Piston Set

If you're building a high-performance Chevrolet LS engine for serious racing or heavy-duty applications, this Wiseco Professional Series piston set is a solid choice. These pistons are specifically designed for a 4.185-inch bore and feature a 1.165-inch compression height with a -23.00cc dish, making them suitable for various compression ratio targets. They are engineered and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for handling the extreme pressures of racing.

Wiseco has packed these pistons with features aimed at durability and performance. You'll find precision ring grooves, an anti-detonation groove, and additional ring seal improvements to ensure consistent power delivery and longevity. The piston crowns are fully machined for accuracy, and they incorporate forced pin oiling to keep the wrist pins properly lubricated under high stress. Furthermore, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, contributing to overall engine health and efficiency during demanding use.

This set includes eight pistons, enough for a complete V8 engine. Remember 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.
