What does 0.50mm oversized mean for these rod bearings?

This means the bearings are designed to be used when the engine's crankshaft journals have been machined down by 0.50mm. This allows for the restoration of proper oil clearance and oil pressure in a worn or rebuilt engine.

Are these bearings compatible with all Mitsubishi 4G63 engines?

These bearings are specifically designed for the 7-bolt version of the Mitsubishi 4G63 and 4G64 engines, commonly found in DSM and EVO I-IX models, as well as the specified Kia Optima models.

What is the typical application for these types of bearings?

These bearings are typically used during an engine rebuild or overhaul. They are essential for ensuring proper oil clearance and lubrication between the connecting rod and the crankshaft.

Product Details

You get a full set of 0.50mm oversized rod bearings in this kit, which means one box handles the critical bearing replacement for your engine rebuild. These ACL bearings are specifically made for the Mitsubishi 4G63 and 4G64 7-bolt engines found in certain DSM and EVO models, and importantly, they also fit your 2001-2006 Kia Optima. Replacing rod bearings is a key step when rebuilding an engine, especially if you're dealing with wear or preparing for higher performance applications.

ACL has been making engine bearings for a long time, and they're known for well-built parts. These are 0.50mm oversized, meaning they're designed to be used when the crankshaft journals have been machined down by 0.50mm. This allows you to restore proper clearances and oil pressure in an engine that has seen significant wear or has been rebuilt with a reground crankshaft. Using the correct size bearing is crucial for proper oil flow and bearing life.

When you're putting an engine back together, getting the bearing clearances right is essential for longevity and performance. Make sure to follow the manufacturer's installation instructions and torque specifications carefully during assembly.
