When you're upgrading your rods and pistons, it's smart to replace 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 harm the crankshaft and other parts. ACL's top - quality rod bearings are designed to be durable and strong. They prevent fatigue and failure and reduce stress on the drivetrain. Remember, Subaru rod bearings come in 48mm or 52mm journal sizes. The journal size isn't based on the VIN or year, so you need to measure it before buying. Engine internals aren't eligible for exchange or return, so be sure which bearings you need.

Using these ACL rod bearings is simple. When you're working on upgrading your rods and pistons, just replace the old rod bearings with these new ones. But before you buy, make sure to measure the journal size of your engine as it's either 48mm or 52mm. This size isn't related to the VIN or the year of your car. Since engine internals can't be exchanged or returned, double - check what you need. To keep these bearings in good shape, follow your car's regular maintenance schedule. If you notice any strange noises or vibrations from your engine, it's a good idea to have a professional take a look at the bearings right away.
