ACL Rod Bearing High Performance Standard Size Set 52mm Journal Bearing WRX 2002-2014 / STI 2004-2021 Subaru Turbo Models | 4B8296H-STD

When upgrading rods and pistons, it's smart to replace rod bearings too. Main bearings play a key role in preventing 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 designed to be durable and strong. They prevent fatigue and failure, and reduce stress on the drivetrain. Subaru rod bearings come in 48mm or 52mm journal sizes. Journal size isn't determined by VIN or year, so measure it before buying. Engine internals can't be exchanged or returned, so be sure you get the right bearings. These bearings fit Subaru EJ20/EJ22/EJ25 models.

Using these ACL rod bearings is straightforward. When you're working on upgrading your rods and pistons, simply install the bearings as part of the process. Make sure to measure the journal size accurately before purchase. Since engine internals can't be returned, double - check this measurement. As for maintenance, keep an eye on the engine's performance. If you notice any unusual noises or vibrations, it might be time to inspect the bearings. Regular engine check - ups can help you catch any issues early. Also, follow the manufacturer's recommended oil change schedule to keep the bearings well - lubricated and in good condition.
