ACL Rod Bearing High Performance Standard Size with Extra Oil Clearance Set 48mm Journal Bearing WRX 2002-2014 / STI 2004-2021 Subaru Turbo Models | 4B8320HX-STD

When replacing rods and pistons, it's smart to change the rod bearings too. Good support from main bearings stops oscillations and wear that can harm the crankshaft and other parts if the engine gets out of balance. ACL's high - quality rod bearings are tough and strong. They prevent fatigue and failure, and lower drivetrain stress. Note: Subaru rod bearings come in 48mm or 52mm journal sizes. Measure the journal size before buying, as engine internals can't be exchanged or returned.

Using these ACL rod bearings is straightforward. When you're replacing the rods and pistons in your Subaru turbo (WRX 2002 - 2014 or STI 2004 - 2021), just take out the old rod bearings and put these new ones in. Before buying, make sure to measure the journal size. It's either 48mm or 52mm, and it's not related to the VIN or year. Once installed, these bearings will prevent fatigue and reduce drivetrain stress. 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. Remember, engine internals like these bearings can't be exchanged or returned, so double - check your needs before purchase.
