When you're working on rods and pistons, it's smart to replace the rod bearings too. Main bearings play a key role in providing proper support. They prevent oscillations and wear, which can harm the crankshaft and other parts if the engine gets out of balance. ACL's high - quality rod bearings are designed to be durable and strong. They stop fatigue and failure while reducing drivetrain stress. Remember, Subaru rod bearings come in 48mm or 52mm journal sizes. The journal size isn't determined by VIN or year; you need to measure it before buying. Since engine internals aren't eligible for exchange or return, make sure you pick the right bearings.

Using these ACL rod bearings is straightforward. When you're working on your Subaru WRX or STI engine's rods and pistons, just replace the old rod bearings with these new ones. It's important to measure the journal size accurately before buying. Don't rely on the VIN or the year of the car; always take a measurement. Once installed, these bearings will help keep your engine running smoothly by preventing wear and fatigue. As 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. Also, follow your car's regular maintenance schedule to ensure the bearings last as long as possible. And remember, since these are engine internals, they can't be exchanged or returned, so double - check your selection before purchasing.
