Wiseco GM ECOTEC 10:1 CR FT 1.053 X 86.5 Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston kit is built for serious racers and builders who need parts that can handle heavy to severe duty. These pistons are designed to replace your stock ones in GM Ecotec engines, offering a 10:1 compression ratio with a bore of 86.50 mm. They fit a range of vehicles, including models like the Chevrolet Cobalt, Pontiac G5, and Saturn Ion.

Each piston is forged and machined in the USA from 2618 aluminum, chosen for its improved tensile strength. You'll find precision ring grooves, anti-detonation features, and additional ring seal improvements to help keep things running smoothly under pressure. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are details that show these are built for demanding performance builds where reliability is key.

This kit includes four pistons, ready to be installed in your engine. Remember that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
