Wiseco Chevy LS 4.155in Bore 4.000in Stroke 1.110in CH -25.00 CC Piston Shelf Stock Kit - Set of 8

Forged from 2618 aluminum, these Wiseco Professional Series pistons are built for the demands of serious racing and heavy-duty performance builds. This set is specifically designed for Chevrolet LS engines, featuring a 4.155-inch bore and a 4.000-inch stroke. The -25.00cc dish in the piston crown helps achieve a specific compression ratio tailored for high-performance applications.

Wiseco has packed these pistons with features aimed at improving both performance and longevity. You'll find precision-machined ring grooves, anti-detonation grooves, and additional features designed to enhance ring seal. The pistons also come with ArmorGlide skirt coating, which helps resist seizure, reduces friction for smoother operation, and contributes to quieter running. The fully machined crown and forced pin oiling further underscore the commitment to durability and performance in severe duty conditions.

This kit includes a set of eight pistons, along with premium rings, ready for your next engine build. 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 assembly and break-in procedures.
