ACL Rod Bearing High Performance 0.025mm Oversized Set 48mm Journal Bearing WRX 2002-2014 / STI 2004-2021 Subaru Turbo Models | 4B8320H-.025

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 - notch rod bearings are built tough. They prevent fatigue and failure, and also reduce stress on the drivetrain. Before buying, note that Subaru rod bearings are for either 48mm or 52mm journal sizes. The journal size isn't related to the VIN or year, so you need to measure it first. Remember, engine internals can't be exchanged or returned, so make sure you pick the right bearings.

Using these ACL rod bearings is easy. When you're replacing the rods and pistons in your Subaru turbo model (WRX 2002 - 2014 or STI 2004 - 2021), simply install these bearings as part of the process. But here's what you need to watch out for. First, always measure the journal size of your engine before you buy. It's either 48mm or 52mm, and this measurement isn't based on the VIN or the year of your car. Since engine internals can't be returned or exchanged, double - check this size. As for maintenance, these bearings are designed to be durable. However, keep an eye on your engine's performance. If you notice any strange noises or a drop in power, it might be time to inspect the bearings. Regular engine checks can help catch any issues early and keep your car running smoothly.
