Wiseco Mits Turbo DISH -21cc 1.130 X 85.5 Piston Shelf Stock Kit

Wiseco is well-known for building strong, reliable internal engine components, especially for performance applications. Now, let's talk about this specific piston kit, the K571M855, designed for your 1990-1992 Eagle Talon, Mitsubishi Eclipse, Mitsubishi Galant, or Plymouth Laser equipped with the 4G63 engine. These aren't just any pistons; they are part of Wiseco's Professional Series, meaning they're built with no compromises for serious racers and builders who demand the best for heavy to severe duty race builds.

Crafted from 2618 aluminum right here in the USA, these pistons are forged and machined for improved tensile strength, which is crucial when you're pushing your engine hard. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, all contributing to better performance and durability under extreme conditions. You'll also find a fully machined crown and forced pin oiling to keep things well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, making for a quieter and more resilient operation.

This set includes four pistons, each with a -21cc dish volume and a bore size of 85.50 mm. The compression height is 28.70 mm, and they use a 0.827-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a serious engine build where reliability and performance under extreme stress are paramount, this Wiseco piston kit is a solid choice.
