Your high - performance engine build demands top - notch internal components. King Engine Bearings are engineered to handle the highest loads and RPMs. They feature the industry's tightest wall tolerances, with shells matched to 0.0001'. The greater rod bearing height enhances bearing - to - bore contact and heat transfer, significantly reducing the risk of spinning at high RPMs. The enlarged and chamfered oil holes ensure equal oil distribution under heavy load, making these bearings tough enough for high - temperature, high - speed engine operation. King offers the widest range of sizing options, including special clearances for custom builds.
XP Bearings are ideal for dedicated track use or street cars in extended racing events. Made from enhanced tri - metal copper lead construction with a nickel barrier fused via a SecureBond adhesion process, they have a 15% - 30% higher load capacity than traditional bearings. The 0.0005' metallurgical enhanced and hardened performance overlay provides extended fatigue resistance. XP main bearings are 1/2 grooved for maximum lower shell load capacity.
Please note: Engine bearings need proper tolerance measurement before purchase. If you're unsure about the size, consult a professional engine builder. We can't accept returns or exchanges for incorrectly ordered engine internal components. Size: (Suites 52mm Journal Size)
These King Engine Rod Bearings are great for your high - performance Subaru WRX or STI engine. Before you buy, you need to measure the proper tolerance of your engine. If you're not sure, ask a professional engine builder. When installing, make sure the bearings are properly placed and aligned to ensure good contact and heat transfer. During use, keep an eye on the engine's performance. If you notice any unusual noises or vibrations, it could be a sign of a problem. For maintenance, change the engine oil regularly as recommended by your vehicle's manufacturer. This will help keep the bearings lubricated and in good condition. Remember, these bearings are designed for high - load and high - RPM operation, but they still need proper care to last.
