Main Bearings

Your high performance engine build deserves the most advanced internal components designed to withstand the highest loads and RPMs. So what makes King Engine Bearings track tough and street smart? All King bearings are designed with the closest wall tolerances in the industry, with all shells matched to 0.0001". Greater rod bearing height improves bearing-to-bore contact and heat transfer, greatly reducing spin potential at high RPMs. Utilizing enlarged and chamfered oil holes for equal distribution under heavy load, King bearings are built tough enough for even the highest temperatures at the fastest engine speeds. Versatility is the name of the game which is why King offers the industry's widest selection of sizing including special clearance options for advanced custom builds.

XP Bearings: XP bearings are designed for dedicated track applications or street cars that may see extended circle track racing or endurance events. Formed from enhanced tri-metal copper lead construction, XP bearings utilize a nickel barrier fused with a SecureBond adhesion process. XP bearings feature a 15%-30% greater load capacity than traditional bearings and 0.0005" matallurgically enhanced and hardened performance overlay for extended fatigue resistance. XP main bearings are 1/2 grooved for uncompromised lower shell load capacity.

Please Note When Ordering Bearings:

Engine bearings require proper tolerance to be measured before purchase. If you are not sure what size bearings your build requires, please consult a professional engine builder. We are not responsible for incorrectly ordered bearings and can not take returns or provide exchanges on any engine internal components.
