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 built tough. They prevent fatigue and failure and reduce stress on the drivetrain. Know exactly what you're buying: Subaru rod bearings come in 48mm or 52mm journal sizes. The journal size isn't related to the VIN or the year of the car. You must measure it before buying. Make sure you pick the right bearings because engine internal components can't be exchanged or returned.

Using these ACL rod bearings is simple. When you're replacing your rods and pistons, just swap out the old rod bearings with these new ones. Before you buy, always measure the journal size to make sure you get the right fit. It's crucial as engine internals can't be returned. As for maintenance, keep an eye on the engine's performance. If you notice any strange noises or vibrations, it might be time to check the bearings. Regular oil changes also help keep the bearings in good shape and reduce wear and tear.
