Your high - performance engine build demands top - notch internal components that can handle high loads and RPMs. King Engine Bearings are the answer. They're designed with the tightest wall tolerances in the industry, and all shells are matched to 0.0001'. The greater rod bearing height enhances bearing - to - bore contact and heat transfer, reducing the risk of spinning at high RPMs. With enlarged and chamfered oil holes for equal distribution under heavy load, these bearings can withstand the highest temperatures at high engine speeds. King offers the industry's widest range of sizing, including special clearance options for custom builds. XP Bearings are ideal for track use or street cars in endurance events. Made from enhanced tri - metal copper lead construction with a nickel barrier and SecureBond adhesion process, they have 15% - 30% greater load capacity than traditional bearings and a 0.0005' metallurgically enhanced overlay for better fatigue resistance. XP main bearings are 1/2 grooved for uncompromised lower shell load capacity. When ordering bearings, measure proper tolerance first. If unsure, consult a professional engine builder. Subaru main bearings are specific to the #5 journal position, which must be known before purchase. Engine internals are non - returnable and non - exchangeable.
How to use: Before installing the King Engine Main Bearings, make sure to measure the proper tolerance for your engine. If you're not confident, it's best to consult a professional engine builder. Once you've got the right size, carefully install the bearings according to the engine's specifications. Note that Subaru main bearings are specific to the #5 journal position, so know this before buying. Maintenance advice: Regularly check the engine oil level and quality. Good oil helps keep the bearings lubricated and reduces wear. Also, keep an eye on the engine temperature. Overheating can damage the bearings. If you notice any strange noises or performance issues from your engine, have it inspected as soon as possible. Remember, engine internal components like these bearings can't be returned or exchanged, so be careful when ordering.
