What does the +0.25mm size mean for these bearings?

The +0.25mm size indicates that these bearings are intended for use with crankshaft journals that have been machined down by 0.25mm. This is common during an engine rebuild when the crankshaft has been resurfaced due to wear or damage.

What is the 'MC' designation in the part number?

The 'MC' in the part number stands for King's 'Machining Control' feature. This design helps the bearing maintain its intended shape under engine load, which is important for consistent oil clearance and preventing premature wear.

What are these bearings made of?

These bearings feature a multi-layer construction. They have a strong steel backing for structural integrity and a babbit overlay, which is a soft metal alloy that provides a smooth surface for the crankshaft to rotate against.

About this part

Product Details

These King Engine Bearings rod bearings are built with a multi-layer material construction, featuring a steel backing for strength and a babbit overlay for smooth operation against the crankshaft. This set is specifically sized at +0.25mm, meaning it's intended for crankshaft journals that have been machined down by that amount during an engine rebuild. They are designed for Chrysler 345 and 370 cubic inch, 16-valve engines, commonly found in various Dodge and Chrysler vehicles.

The 'MC' in the part number indicates King's 'Machining Control' feature, which helps ensure the bearing's shape stays true under load, reducing the risk of oil film collapse and improving overall engine reliability. This attention to detail in their construction helps these bearings perform well in demanding engine conditions, offering a solid option for rebuilding your engine's bottom end.

When rebuilding an engine, using bearings that are precisely sized for the machined crankshaft is crucial for proper oil clearance and long-term durability. This set provides that precision for engines that have had their crank journals turned down by 0.25mm.
