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

When replacing rods and pistons, it's smart to change the rod bearings too. Good support from main bearings is key to stop oscillations and wear that can harm the crankshaft and other parts if the engine gets out of balance. ACL's top - notch rod bearings are designed to be durable and strong. They prevent fatigue and failure, and reduce stress on the drivetrain. Know your purchase: Subaru rod bearings come for either 48mm or 52mm journal sizes. The journal size isn't based on VIN or year; you must measure it before buying. Make sure you pick the right bearings as engine internal components can't be exchanged or returned.

How to use: When you're working on replacing the rods and pistons in your Subaru WRX 2002 - 2014 or STI 2004 - 2021 turbo models, it's the perfect time to put in these ACL rod bearings. Just follow the normal engine disassembly and assembly procedures. Before you buy, measure the journal size of your engine to ensure you get the right 48mm or 52mm bearings. Note: Engine internal components like these rod bearings can't be exchanged or returned, so double - check your measurements. Maintenance: These bearings are built to last, but regular engine maintenance will keep them in top shape. Check your engine oil regularly and change it as recommended by the manufacturer. This will help reduce wear and keep the drivetrain stress low.
