ACL Rod Bearing High Performance 0.50mm Oversized Set 48mm Journal Bearing WRX 2002-2014 / STI 2004-2021 Subaru Turbo Models | 4B8320H-.50

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 damage the crankshaft and other parts. ACL's top - quality rod bearings are built tough. Their durable design prevents 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 VIN or year, so you need to measure it before buying. Since engine internals can't be exchanged or returned, make sure you pick the right bearings.

Using these ACL rod bearings is straightforward. When you're 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. Before buying, always measure the journal size of your engine. It can be either 48mm or 52mm. Make sure to double - check which size you need as you can't exchange or return engine internals. To keep these bearings in good shape, regularly check your engine's oil levels and quality. Clean oil is important for reducing wear and tear. If you notice any strange noises or performance issues, have your engine checked by a professional right away.
