ACL Main Bearing Duraglide 0.25mm Oversized Set, #3 Thrust Bearing Position WRX 2002-2014 / STI 2004-2021 Subaru Turbo Models | 5M8297A-.25

ACL's main bearings are crafted from a softer metal to safeguard your crank and engine block from wear. A thin oil layer lubricates the bearings - crank connection, enabling the crank to 'float' and minimizing wear. Proper support from these bearings is vital to prevent oscillations and wear that can harm the crankshaft and other parts as the engine goes 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. These are recommended for experienced professionals only. Note that Subaru main bearings are specific to either #5 or #3 journal bearing positions. The journal bearing position isn't related to VIN or year, and you must know it before buying. Engine internals aren't eligible for exchange or return, so be sure of your needs.

How to use: Install these main bearings carefully in the correct journal bearing position (#3 in this case) as per your Subaru model's requirements. Make sure the connection between the bearings and the crank is well - lubricated with oil. Precautions: Only experienced professionals should buy and install these bearings. Know the correct journal bearing position before purchase, as engine internals can't be exchanged or returned. Maintenance advice: Regularly check the oil level and quality. Since bearings with extra oil clearance wear more during startup, start the engine smoothly to reduce unnecessary stress on the bearings. Keep an eye on the engine's balance and performance to detect any potential issues early.
