What does the '+0.75mm' size designation mean for these bearings?

The '+0.75mm' indicates that these bearings are 0.75mm undersize. This means they are designed to fit a crankshaft that has been machined down by 0.75mm during an engine rebuild to ensure proper clearance.

What is the advantage of a tri-metal bearing construction?

Tri-metal bearings, like these from King, use multiple layers of different materials. This construction offers excellent embeddability, meaning they can conform to minor imperfections in the crankshaft, and provides good compatibility with various engine oils for reliable performance.

Are these bearings a direct replacement for stock size?

No, these bearings are specifically sized at 0.75mm undersize. They are intended for engine rebuilds where the crankshaft has been machined to match this undersize specification, not for a stock-sized crankshaft.

About this part

Product Details

These King Engine Bearings connecting rod bearings are built with a high-performance tri-metal overlay, a popular choice for rebuilding engines where durability and consistent oil clearance are key. They are specifically sized at 0.75mm undersize, meaning they are intended for crankshafts that have been machined down by that amount during an engine rebuild. This set is designed for Mazda F8 engines found in models like the 626, and Kia Besta 2.2D applications.

The tri-metal construction offers excellent embeddability and compatibility with various oil types, helping to protect your crankshaft journals. King uses a specialized bonding process to ensure the layers of material stay put, even under the stress of engine operation. This means you get reliable performance and extended bearing life, which is crucial when you're putting an engine back together.
