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 you're replacing rods and pistons, it's smart to swap out the rod bearings too. Good support from main bearings is super important. It stops oscillations and wear that can harm the crankshaft and other parts if the engine gets out of balance. ACL's top - quality rod bearings are built tough. Their durable design prevents fatigue and failure, and also cuts down on drivetrain stress. Here's what to know before you buy: Subaru rod bearings come in 48mm or 52mm journal sizes. The journal size isn't based on the VIN or the year of the car. You have to measure it before buying. Make sure you pick the right bearings because engine internal components can't be exchanged or returned.

Using these ACL rod bearings is easy. When you're working on replacing rods and pistons, simply take out the old rod bearings and put these new ones in. Remember, it's crucial to measure the journal size accurately before buying to ensure you get the right fit (either 48mm or 52mm). Once installed, these bearings will do a great job of preventing engine wear and stress. As for maintenance, keep an eye on your engine's performance. If you notice any strange noises or vibrations, it could be a sign that the bearings need to be checked. Regular engine oil changes are also important to keep the bearings lubricated and in good condition. And since these are engine internal components, they can't be exchanged or returned, so double - check your measurements before making the purchase.
