ACL Rod Bearing High Performance Standard Size Set 48mm Journal Bearing WRX 2002-2014 / STI 2004-2021 Subaru Turbo Models | 4B8320H-STD

When you're replacing rods and pistons, it's smart to swap out the rod bearings too. Main bearings play a key role in preventing oscillations and wear. If the engine gets out of balance, it can damage the crankshaft and other parts. ACL's top - quality rod bearings are designed to be durable and strong. They prevent fatigue and failure and also reduce stress on the drivetrain. Note: Subaru rod bearings come in 48mm or 52mm journal sizes. The journal size isn't determined by the VIN or the year. You need to measure it before buying. Make sure you pick the right bearings as engine internals can't be exchanged or returned.

Using these ACL rod bearings is simple. When you're working on replacing the rods and pistons in your Subaru Turbo Model (WRX 2002 - 2014 or STI 2004 - 2021), just take out the old rod bearings and put these new ones in. But before you buy, measure the journal size. It can be either 48mm or 52mm. Remember, you can't exchange or return engine internals, so double - check. 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. Regular engine servicing will also help keep these bearings in good shape and your engine running smoothly.
