What does the +1.0mm sizing mean for these bearings?

The +1.0mm sizing indicates that these bearings are designed for a crankshaft that has been machined down by 1 millimeter. This is typically done to account for wear on the original crankshaft or as part of a performance engine build to achieve specific clearances.

What is the material of these connecting rod bearings?

These bearings are made with a bimetal construction that utilizes an aluminum silicon base. This material is chosen for its ability to handle heat and provide a durable bearing surface for the crankshaft.

Do these bearings come with installation hardware?

This product is for the connecting rod bearings only. Installation hardware, such as new rod bolts, is typically sold separately and should be sourced according to your engine's service manual specifications.

About this part

Product Details

If you're rebuilding the bottom end of your Mitsubishi 4G63 or 64 DOHC engine, a fresh set of connecting rod bearings is essential. These bearings sit between the connecting rod and the crankshaft, allowing them to spin smoothly while handling the immense forces generated during combustion. This set from King Engine Bearings is specifically sized at +1.0mm, meaning it's intended for use with a crankshaft that has been machined down by 1 millimeter to account for wear or to achieve a specific build tolerance.

King uses a bimetal construction with an aluminum silicon base for these bearings. This material choice helps manage heat and provides a solid surface for the crankshaft to ride on. Because these are a +1.0mm undersize bearing, they are designed to be used with a crankshaft that has been ground down by that amount. This is a common practice when rebuilding engines that have seen significant mileage or if you're building a performance engine where tighter tolerances are desired.

This set is designed to fit a wide range of vehicles that use the 4G63 or 64 DOHC engine, including popular models like the Mitsubishi Eclipse, Dodge Stratus, and Hyundai Sonata. Always confirm fitment for your specific vehicle and ensure your crankshaft has been properly machined to the +1.0mm undersize before installation.
