King Engine Bearings Mitsubishi 4B11T Turbo Evo X/2007+ (Size +0.50mm) Main Bearing Set

This is a main bearing set from King Engine Bearings, specifically made for the 4B11T turbo engine found in the Mitsubishi Lancer Evolution X and compatible with your 2011-2021 Mitsubishi Outlander Sport. Main bearings are crucial components that support the crankshaft within the engine block, allowing it to rotate smoothly while handling significant loads. When rebuilding or repairing your engine, especially one with a turbocharger, ensuring these bearings are in top condition is vital for engine longevity and performance.

This particular set is constructed from a strengthened aluminum bimetal material. This type of bearing is well-built for the demands of a performance engine, offering good wear resistance and load-carrying capacity. The bearings in this set are sized at +0.50mm, meaning they are intended for use when the crankshaft journals have been machined down by 0.50mm to correct for wear or damage. Using the correct bearing size is essential for maintaining proper oil clearance, which is critical for lubrication and preventing premature wear.

When installing these bearings, it's important to follow the manufacturer's recommended procedures, including proper cleaning of the crankshaft and block surfaces, and ensuring correct oil clearances are achieved. This set is designed as a direct fit for the specified applications, simplifying the installation process for a mechanic.
