When 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 - notch rod bearings are built tough. Their durable design prevents fatigue and failure while reducing stress on the drivetrain. Know your needs: Subaru rod bearings come in 48mm or 52mm journal sizes. You must measure the journal size before buying; it's not related to the VIN or year. Engine internals can't be exchanged or returned, so be sure which bearings you need. Fitment: Subaru EJ20/EJ22/EJ25.

Using these ACL rod bearings is simple. When you're in the process of replacing rods and pistons in your Subaru engine, just swap out the old rod bearings with these new ones. Before you buy, always measure the journal size of your engine to make sure you get the right fit. Remember, these are specific to 48mm or 52mm journal sizes and are not determined by the VIN or year. Since engine internals can't be returned or exchanged, double - check your measurements. As for maintenance, keep an eye on your engine's performance. If you notice any strange noises or vibrations, it could be a sign that the bearings need to be inspected. Regular engine servicing will also help keep these bearings in good shape for a long time.
