ACL Main Bearing High Performance 0.25mm Oversized Set, #3 Thrust Bearing Position WRX 2002-2014 / STI 2004-2021 Subaru Turbo Models | 5M8297H-.25

ACL's main bearings are crafted from a softer metal. This design protects your crank and engine block from excessive wear. A thin oil layer lubricates the bearing - crank connection, letting the crank 'float' and minimize wear. Main bearings are vital for proper support, preventing oscillations and wear that can harm the crankshaft and other parts when the engine goes out of balance. Bearings with extra oil clearance can handle higher - horsepower motors better, but they may wear more during startup. We suggest these be bought by experienced pros only. Remember, Subaru main bearings are specific to either #5 or #3 journal bearing positions. This isn't related to VIN or year. Know what you need before buying as engine internals aren't eligible for exchange or return.

How to use: Install these main bearings in your Subaru turbo model's engine according to the #3 thrust bearing position. Make sure to have all the necessary tools ready. When starting the engine, be aware that bearings with extra oil clearance may experience more wear at startup. Note: Always know the correct journal bearing position before you buy. Engine internals like these bearings are non - returnable and non - exchangeable. Maintenance: Regularly check the oil level and quality. A good oil supply helps keep the bearings lubricated and reduces wear. If you notice any unusual noises or performance issues, have the bearings inspected by a professional.
