ACL Rod Bearing High Performance 0.25mm Oversized Set 52mm Journal Bearing WRX 2002-2014 / STI 2004-2021 Subaru Turbo Models | 4B8296H-.25

When you're replacing rods and pistons, it's smart to swap out the rod bearings too. Good support from main bearings is key to stop oscillations and wear. If the engine gets out of balance, it can harm the crankshaft and other parts. ACL's top - quality rod bearings are built tough. Their durable design stops fatigue and failure, and reduces stress on the drivetrain. Remember, Subaru rod bearings come in 48mm or 52mm journal sizes. The journal size isn't based on the VIN or year; you need to measure it before buying. Since engine internals can't be exchanged or returned, make sure you get the right bearings. These bearings fit Subaru EJ20/EJ22/EJ25 models.

Using these ACL rod bearings is straightforward. When you're replacing rods and pistons, just install these bearings as part of the process. But there are some important things to note. First, always measure the journal size before you buy. You can't rely on the VIN or the year of your Subaru; it has to be a direct measurement. Once you've installed the bearings, keep an eye on your engine's performance. If you notice any strange noises or vibrations, it could be a sign of an issue. For maintenance, follow your Subaru's regular service schedule. Keep the engine oil clean and at the right level, as good lubrication is crucial for the bearings' long - term performance. Also, avoid pushing your engine too hard right after installing new bearings. Give them some time to settle in.
