Wiseco GM LD9 2.4L Dished -7.5cc 9:1 Piston Shelf Stock

If you're rebuilding the engine in a Sport Compact vehicle like a Chevrolet Cavalier, Pontiac Sunfire, or Buick Skylark from the mid-90s to early 2000s, these Wiseco pistons are a solid option. They are designed for the LD9 2.4L engine and feature a dished crown that results in a 9:1 compression ratio, making them suitable for builds that need a bit more durability than stock.

Wiseco forges these pistons from 2618 aluminum right here in the USA, which gives them improved tensile strength over other materials. They come with precision-machined ring grooves, an anti-detonation groove, and features to help seal the rings better, all contributing to better performance and durability under heavy use. You'll also find an ArmorGlide skirt coating that helps reduce friction, resist seizure, and keep things quieter. The fully machined crown and forced pin oiling are details that show these are built for demanding applications.

This set is for a single piston and includes premium rings. Keep in mind 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.
