When you're working on your rods and pistons, it's smart to replace the rod bearings too. Good support from the 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 - quality rod bearings are designed to be tough and strong. They prevent fatigue and failure and reduce stress on the drivetrain. Before buying, know that Subaru rod bearings come in 48mm or 52mm journal sizes. You can't tell the journal size from the VIN or the year; you have to measure it. Make sure you pick the right bearings as engine internal components can't be exchanged or returned.

Using these ACL rod bearings is straightforward. When you're replacing your rods and pistons, just swap out the old rod bearings with these new ones. Remember, proper support from the main bearings is key to keeping your engine running smoothly. As for the journal size, don't rely on the VIN or the year. You've got to measure it before buying to ensure you get the right fit. And once you've installed the bearings, there's not much maintenance needed. But keep an eye on your engine's performance. If you notice any strange noises or changes, it could be a sign that something's wrong. Since these are engine internal components, they can't be exchanged or returned, so double - check your measurements to avoid any issues.
