Part #: KIT-ENGBEAR-1. When replacing rods and pistons, it's smart to change the rod bearings too. Main bearings are super important as they offer proper support. They stop oscillations and wear that can harm the crankshaft and other parts if the engine gets out of balance. ACL's high - quality rod bearings are designed to be durable and strong, preventing fatigue and failure while reducing drivetrain stress. ALC's main bearings are made of softer metal, which protects your crank and engine block from wear. There's also a thin oil layer between the bearings and the crank. This allows the crank to 'float', cutting down on wear. Main bearings are essential to avoid oscillations and wear as the engine moves out of balance. Included: 1x ACL Subaru EJ20/EJ22/EJ25 (For Thrust in #5 Position) Standard Size High Performance Main Bearing Set P/N: 5M8309H - STD and 1x ACL Subaru EJ20/EJ22/EJ25 (Suites 52mm Journal Size) Standard Size High Performance Rod Bearing Set P/N: 4B8296H - STD. Fitment: 02 - 14 WRX, 04 - 21 STI. Please note: Does NOT fit 2015+ Subaru WRX.
Using this ACL engine bearing kit is straightforward. First, when you're replacing the rods and pistons in your Subaru WRX (2002 - 2014) or STI (2004 - 2021), make sure to install the rod bearings included in the kit. Then, carefully place the main bearings in the right positions to support the engine properly. It's important to remember that this kit won't fit Subaru WRX models from 2015 onwards. For maintenance, regularly check the oil level and quality. The thin layer of oil between the bearings and the crank is crucial for reducing wear. If you notice any strange noises or vibrations from the engine, it might be a sign to inspect the bearings. Keep the engine clean to prevent dirt and debris from causing damage to the bearings. Overall, this kit is designed to be durable, but proper care will ensure it lasts a long time and keeps your engine running smoothly.
