ACL Main Bearing Duraglide 0.50mm Oversized Set, #3 Thrust Bearing Position WRX 2002-2014 / STI 2004-2021 Subaru Turbo Models | 5M8297A-.50

ACL's main bearings are crafted from a softer metal to protect your crank and engine block from wear. A thin oil layer lubricates the connection between the bearings and the crank, letting the crank 'float' and minimizing wear. Proper support from these main bearings is vital to prevent oscillations and wear that can harm the crankshaft and other parts as the engine gets out of balance. Bearings with extra oil clearance can handle the stress of high - horsepower motors better, but they'll experience more wear during startup. We suggest that only experienced professionals buy these. Note that Subaru main bearings are specific to either #5 or #3 journal bearing positions. This position isn't determined by VIN or year, and you must know it before buying. Since engine internal components aren't eligible for exchange or return, make sure you pick the right bearings.

How to use: These main bearings are designed to be installed in your Subaru's engine. When installing, ensure you've correctly identified the #3 journal bearing position. Make sure to clean the crank and engine block thoroughly before installation to prevent any debris from causing damage. Notice: Only experienced professionals should install these bearings, especially considering the extra oil clearance ones which can wear out faster during startup. It's crucial to know the correct journal bearing position before purchasing as engine internals can't be returned or exchanged. Maintenance advice: Regularly check the oil level and quality. Good oil lubrication is key to the long - term performance of these bearings. If you notice any unusual noises or vibrations from the engine, it might be time to inspect the bearings for wear.
