Wiseco Mitsubishi 4G63T 86.75 mm Bore 34.87 mm CH -4.75 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty engine builds. The 86.75 mm bore size is specific for certain 4G63T engine configurations, and the 34.87 mm compression height along with a -4.75 CC dish volume are critical measurements for achieving your desired compression ratio. Wiseco machines these pistons in the USA, ensuring precise tolerances for performance and durability.

Beyond the base material, these pistons feature several enhancements for improved performance and longevity. The ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and a longer lifespan under stress. You'll also find precision ring grooves, anti-detonation grooves, and additional features designed to improve ring seal, which is crucial for maintaining compression and preventing blow-by in high-performance engines. The fully machined crown and forced pin oiling further underscore their design for severe duty applications.

This set includes four pistons, ready for your 4G63T engine build. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper assembly and break-in procedures.
