When replacing rods and pistons, it's smart to change the rod bearings too. Proper support from main bearings is vital to avoid 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 to be durable and strong, preventing fatigue and failure while reducing drivetrain stress. Know exactly what you're buying: Subaru rod bearings are for either 48mm or 52mm journal sizes. The journal size isn't based on VIN or year; you must measure it before buying. Make sure you pick the right bearings as engine internal components can't be exchanged or returned. Fitment: Subaru EJ20/EJ22/EJ25.

Using these ACL rod bearings is straightforward. When you're replacing the rods and pistons in your Subaru WRX 2002 - 2014 or STI 2004 - 2021, just swap out the old rod bearings with these new ones. But here's a key thing: measure the journal size of your engine before you buy. It's either 48mm or 52mm, and it doesn't depend on the year or VIN of your car. Once you've installed the bearings, run your engine as normal. To keep them in good shape, follow your car's regular maintenance schedule. Also, keep an eye on your engine's performance. If you notice any strange noises or vibrations, it might be time to check the bearings. Remember, these engine internal parts can't be returned or exchanged, so double - check your needs before purchasing.
