Wiseco Chevy LS Series -20cc R/Dome 1.110x4.070 Piston Shelf Stock Kit

Starting with the -20cc R/Dome design and a 4.070 inch bore, this Wiseco piston set is built from 2618 aluminum, a material chosen for its improved tensile strength, making these pistons ready for the demands of heavy to severe duty race builds. These aren't just off-the-shelf parts; they're crafted with precision in mind, featuring fully machined crowns and forced pin oiling to ensure consistent lubrication where it's needed most.

Wiseco has packed these Professional Series pistons with features aimed at enhancing performance and durability. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. This attention to detail means you're getting a well-built set designed to handle the stress of high-performance applications.

This kit includes a set of 8 pistons, along with premium rings, ready for installation in your Chevrolet LS engine. 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.
