When you're 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. If the engine gets out of balance, it can damage the crankshaft and other parts. ACL's top - notch rod bearings are built tough. Their strong and durable design helps prevent fatigue and failure, and also cuts down on drivetrain stress. Know Your Purchase: Subaru rod bearings come for either 48mm or 52mm journal sizes. The journal size isn't based on VIN or year; you have to measure it before buying. 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, simply install the new bearings in place of the old ones. But here's what you need to pay attention to. First, always measure the journal size before buying. It's not determined by the VIN or the year of your Subaru. You must get the correct size, or the bearings won't work properly. And remember, engine internal parts like these can't be returned or exchanged, so double - check. For maintenance, keep an eye on your engine's performance. If you notice any strange noises or vibrations, it might be time to check the bearings. Regular engine check - ups are a good idea to make sure the bearings are in good shape and continue to protect your engine from damage.
