When replacing rods and pistons, it's smart to swap out the rod bearings too. Main bearings offer vital support to stop oscillations and wear that can harm the crankshaft and other parts if the engine gets out of balance. ACL's top - notch rod bearings are designed to be durable and strong. They prevent fatigue and failure while reducing drivetrain stress. Note that Subaru rod bearings come in 48mm or 52mm journal sizes. The journal size isn't determined by VIN or year, so measure it before buying. Since engine internals can't be exchanged or returned, make sure you pick the right bearings.

Using these ACL rod bearings is straightforward. When you're replacing your rods and pistons, just take out the old rod bearings and install the new ones. Remember, you need to measure the journal size of your engine before buying these bearings as Subaru engines can have 48mm or 52mm journal sizes. This isn't related to the vehicle's VIN or year. Once installed, these bearings will work to prevent engine issues like fatigue and failure and reduce stress on the drivetrain. As for maintenance, there's not much you need to do. Just keep an eye on your engine's performance. If you notice any strange noises or reduced power, it might be time to check the bearings. And since engine internals aren't returnable or exchangeable, double - check your measurements to ensure you've got the right bearings for your engine.
