Product Description

The King XPC-Series Main Bearings (part MB1322XPC0.25) combine King's race-proven pMaxBlack overlay with an added pMaxKote nano-composite polymer coating for the VW Group V8/V10 engine shared by the Audi R8, Lamborghini Gallardo, and Lamborghini Huracan. This factory-applied coating enhances wear, seizure, and cavitation resistance without changing the bearing's original precision wall thickness.

Built with the same advanced metallurgical and geometric technologies as King's standard XP-Series, these main bearings are engineered for performance applications running forged steel aftermarket crankshafts under sustained high loads. The pMaxBlack tri-metal structure is 24% harder than conventional tri-metal race bearings, providing superior protection against oil starvation during hard use.

This +0.25mm oversize set is sold per main journal for use with a machined or reground crankshaft - always double-check specs with your engine builder before ordering, as this engine platform is shared across Audi, Lamborghini, and related VW Group applications.
