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 providing proper support. They stop oscillations and wear that could damage the crankshaft and other parts if the engine gets out of balance. ACL's top - notch rod bearings are built tough. Their durable design prevents fatigue and failure, and also eases the stress on the drivetrain. Subaru rod bearings come in 48mm or 52mm journal sizes. The journal size isn't determined by the VIN or the year. You must measure it before buying. Remember, engine internal components can't be exchanged or returned, so make sure you get the right bearings.

Using these ACL rod bearings is straightforward. When you're working on replacing rods and pistons in your Subaru Turbo model (WRX 2002 - 2014 or STI 2004 - 2021), just swap out the old rod bearings with these new ones. Before you buy, measure the journal size carefully to ensure you get the right 48mm bearing. Since engine internal parts can't be returned, double - check your measurement. For maintenance, keep an eye on your engine's performance. If you notice any unusual noises or vibrations, it might be time to inspect the bearings. Regular oil changes are also crucial as clean oil helps keep the bearings in good shape and reduces wear and tear.
