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 working on your rods and pistons, it's smart to replace the rod bearings too. Good support from main bearings is super important. It stops oscillations and wear that can mess up the crankshaft and other parts if the engine gets out of balance. 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 exactly what you're buying: Subaru rod bearings come in either 48mm or 52mm journal sizes. The journal size isn't based on the VIN or the year. You have to measure it before you buy. Make sure you pick the right bearings because engine internals can't be exchanged or returned. These bearings fit Subaru EJ20, EJ22, and EJ25 models.

Using these ACL rod bearings is easy. When you're working on your rods and pistons, just replace the old rod bearings with these new ones. But here are some things to keep in mind. First, always measure the journal size before you buy. It's not determined by the VIN or the year, so you need to get an accurate measurement. Also, once you've installed the bearings, make sure they're properly seated to avoid any issues. For maintenance, regularly check the bearings for signs of wear and tear. If you notice any unusual noises or performance issues, it might be time to take a closer look at the bearings. And remember, since engine internals can't be exchanged or returned, double - check your measurements and your needs before making the purchase.
