Wiseco Mitsubishi 4G63 85.00 mm Bore 28.70 mm CH 1.90 CC Piston Set

Forged from 2618 aluminum right here in the USA, these Wiseco pistons are built for the demands of serious racing and performance engine builds. The 85.00 mm bore size is a common upgrade for the Mitsubishi 4G63 engine, and the 28.70 mm compression height is carefully machined to work with specific engine configurations.

Wiseco didn't hold back on the details here. You'll find precision ring grooves designed for a solid seal, along with anti-detonation grooves to help prevent detonation damage under high boost or aggressive tuning. The crown is fully machined for accuracy, and the pistons feature forced pin oiling to keep the wrist pins well-lubricated. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and even quiet things down a bit during operation.

These are intended for heavy to severe duty applications, meaning they're built to handle the kind of stress that comes with high-horsepower builds. If you're putting together a performance engine for track use or serious street driving, these pistons are a well-built foundation.
