King Engine Bearings Main Bearing Set for Mitsubishi 4G63, 4G64 Evo I-IV

XPC Series is King Bearings‘ premium race bearings, featuring the pMaxBlack™ overlay that increases hardness and topped by the innovative pMaxKote™ ceramic nano-composite polymer coating, that enhances wear & seizure resistance without altering the bearing's original wall thickness dimensions.

Commonly use for circle track, drag racing, off-shore, and other applications that utilize steel crankshafts. Features ceramic nano-composite polymer coating, that enhances wear & seizure resistance without altering the bearing's original wall thickness

Tech Features

Copper Based

Tri-Metal Copper based material - Leaded or Lead Free tri layers bearings for low to heavy load engines.

pMaxBlack™

Superior load capacity - Overlay features proprietary nano-scaled hardening process producing superior load capacity.

pMaxKote™

Factory applied polymer coating - Inhouse developed Polymer coating for race applications, enhances seizure & wear resistance, with no added thickness.

U-Groove™

Greater load surface - A 90? oil groove shape, keep oil flow intact, increases bearing load capacity by expanding the surface area.

Radialock™

Optimal crush height and heat transfer - An optimal crush height value obtained from an optimization process of each performance bearing crush height

Eccentrix™

Superior hydrodynamic lubrication - An optimized eccentricity value reached through elasto-hydrodynamic analysis and dynamic calculations.

Bulls Eye™

Perfect clearance in every set - Outperforms the industry’s wall thickness tolerance, ensuring the least thickness variation shell-to-shell.
