Wiseco GM ECOTECH Dished -7cc 8.9:1 86.0 Piston Shelf Stock

If you're working on a Chevrolet Ecotec engine and looking to build for performance, these forged pistons from Wiseco are a solid option. They're designed for a specific bore size of 86.00 mm and feature a dished crown that creates a compression ratio of 8.9:1, which is a common target for boosted or higher-performance naturally aspirated builds on these engines.

Wiseco makes these pistons from 2618 aluminum, a well-known material for its strength in demanding applications. They've included features like precision ring grooves, an anti-detonation groove, and forced pin oiling to help ensure durability and proper lubrication under stress. The piston skirts also have an ArmorGlide coating, which helps reduce friction and resist seizure, making them quieter and more resilient in severe duty builds. These are built to handle heavy use, whether you're racing or just pushing your Ecotec hard.

This piston is sold individually, so be sure to order the correct quantity for your engine. It's designed to fit a range of Chevrolet, Pontiac, and Saturn models from the early 2000s through 2008, so check the fitment details to confirm it's right for your car.
