Wiseco GM LD9 2.4L Dished 9:1 CR 90.5mm Piston Shelf Stock Kit

When you're rebuilding the heart of your performance vehicle, starting with a solid set of pistons is key. This Wiseco Professional Series piston kit gives you four forged pistons, complete with rings and wrist pins, ready to go into your GM 2.4L LD9 engine. These are designed for builders who are serious about performance and durability, whether you're hitting the track or just want a more robust engine for your street machine.

Wiseco crafts these pistons from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial when you're pushing an engine hard. They've also included features like precision ring grooves, anti-detonation grooves, and additional ring seal enhancements to help keep everything running smoothly and efficiently under pressure. The crown is fully machined for accuracy, and the piston skirts come with an ArmorGlide coating. This coating helps reduce friction, resist seizure, and even makes operation quieter, all important factors for a long-lasting, high-performance build.

This kit is built to handle heavy to severe duty applications, meaning they're made for engines that see a lot of stress. The forced pin oiling design also ensures the wrist pins get the lubrication they need. This set is designed to fit a range of vehicles, including popular models like the Chevrolet Cavalier, Pontiac Sunfire, and Buick Skylark from the mid-to-late 90s and early 2000s. Please note that these pistons are not CARB approved and cannot be shipped to California.
