ACL Main Bearing Duraglide 0.75mm Oversized Set, #3 Thrust Bearing Position WRX 2002-2014 / STI 2004-2021 Subaru Turbo Models | 5M8297A-.75

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 cut down on wear. Adequate support from these bearings is vital to prevent oscillations and wear that can harm the crankshaft and other parts when the motor goes out of balance. Bearings with extra oil clearance can handle the stress of high - horsepower motors better, but they'll experience more wear at startup. We advise that only experienced professionals buy these. Note that Subaru main bearings are for either #5 or #3 journal bearing positions. This isn't related to VIN or year; you must know it before buying. Engine internals aren't eligible for exchange or return, so be sure of what you need.

Using these ACL main bearings is straightforward. First, make sure you've correctly identified the journal bearing position (#5 or #3) for your Subaru Turbo model. This is really important as the wrong bearings won't work and can't be returned. Once you've got the right bearings, carefully install them in your engine. They're made of a softer metal to protect your engine parts, and the thin oil layer helps the crank move smoothly. Remember, these bearings with extra oil clearance are great for high - horsepower motors, but they wear more during startup. If you're not an experienced professional, it's a good idea to get some help. For maintenance, regularly check the oil level and quality. Good oil is essential for the bearings to work well and last a long time. Keep an eye on your engine's performance, and if you notice any strange noises or issues, it might be time to check the bearings.
