ACL Rod Bearing High Performance Standard Size with Extra Oil Clearance Set 52mm Journal Bearing WRX 2002-2014 / STI 2004-2021 Subaru Turbo Models | 4B8296HX-STD

When you're replacing rods and pistons, it's smart to swap out the rod bearings too. Good support from main bearings is key to stop oscillations and wear that can harm the crankshaft and other parts if the engine gets out of balance. ACL's top - quality rod bearings are designed tough and durable. They prevent fatigue and failure while reducing stress on the drivetrain. Remember, Subaru rod bearings come in 48mm or 52mm journal sizes. The journal size isn't based on VIN or year; you need to measure it before buying. Since engine internals can't be exchanged or returned, make sure you pick the right bearings. These bearings fit Subaru EJ20/EJ22/EJ25 models.

Using these ACL rod bearings is straightforward. When you're working on your Subaru's engine and replacing rods and pistons, simply take out the old rod bearings and install these new ones. But here's a very important note: always measure the journal size before you buy. You can't rely on the VIN or the year of your car; it has to be a direct measurement. Once installed, your engine will get better support, and it'll be less likely to have issues with fatigue and failure. As for maintenance, keep an eye on your engine's performance. If you notice any strange noises or a drop in power, it might be time to check the bearings. Also, follow your car's regular oil change schedule to keep the bearings well - lubricated and in good shape. And remember, since these are engine internals, they can't be returned or exchanged, so double - check your measurements to make sure you've got the right ones.
