ACL Rod Bearing High Performance 0.025mm Oversized Set 52mm Journal Bearing WRX 2002-2014 / STI 2004-2021 Subaru Turbo Models | 4B8296H-.025

When replacing rods and pistons, it's smart to swap out the rod bearings too. Good support from main bearings is vital to stop oscillations and wear. If the engine gets out of balance, it can harm the crankshaft and other parts. ACL's top - notch rod bearings are designed to be tough and strong. They prevent fatigue and failure and reduce stress on the drivetrain. Know your purchase: Subaru rod bearings come for either 48mm or 52mm journal sizes. You can't tell the journal size from the VIN or year; you have to measure it before buying. Since engine internals aren't returnable, make sure you pick the right bearings. Fitment: Subaru EJ20/EJ22/EJ25.

Using these ACL rod bearings is straightforward. When you're replacing the rods and pistons in your Subaru engine, take out the old rod bearings and put these new ones in. But here's the important part: always measure the journal size before you buy. You can't rely on the VIN or the year of your car. Once you've installed the bearings, make sure everything is properly tightened according to the engine's specifications. As for maintenance, keep an eye on your engine's performance. If you notice any strange noises or vibrations, it could be a sign that something's wrong with the bearings. Also, follow your car's regular service schedule. Changing the engine oil at the recommended intervals will help keep the bearings lubricated and in good condition. Remember, these engine internals aren't eligible for return, so double - check your needs before you purchase.
