Description

The King Racing MB5568XP is part of the XP high-performance bearings series, engineered to meet the extreme demands of race engines. These main bearings utilize advanced metallurgical and geometric technologies, making them ideal for performance applications utilizing forged steel aftermarket crankshafts that experience high loads for extended durations. King Racing's XP series features pMax Black™, a proprietary tri-metal structure that is significantly harder than conventional tri-metal race bearings, ensuring superior durability and performance. Key features of the XP series include Bull's Eye Tolerance for perfect clearance in every set, pMax Black™ for superior load capacity, a U-Groove design to increase the load surface area, and ElliptiX for improved oil ingress. This specific set, part number MB5568XP, is designed as a Standard Green Size main bearing set. These bearings are applications for Honda D16A, D16Z, H22A4, and F23A engines. Each set includes one set of main bearings.
