What does the +0.75mm sizing mean for these bearings?

The +0.75mm sizing indicates that these bearings are 0.75mm larger in diameter than the standard size. This is used when the engine's crankshaft journals have been machined down by 0.75mm to correct wear or runout.

What is the advantage of the tri-metal construction?

The tri-metal construction combines different layers of materials to optimize performance. It typically includes a steel backing for strength, a copper-lead layer for load-carrying capacity, and a tin-aluminum layer for reduced friction and improved wear resistance.

Are these bearings suitable for a stock engine rebuild?

These bearings are specifically sized at +0.75mm, which is an undersize for a machined crankshaft. They are intended for engines where the crankshaft has already been machined to this specific size, often during a performance rebuild or to correct wear.

About this part

Product Details

These connecting rod bearings from King Engine Bearings are built with a tri-metal material construction, featuring a steel-backed overlay that's been hardened for durability. The overlay itself is a unique combination of copper-lead with a nickel barrier, topped off with a thin layer of tin-aluminum. This advanced material setup is designed to handle the high loads and temperatures found in performance engines, offering improved wear resistance and reduced friction compared to standard bearings.

Specifically sized at +0.75mm, these bearings are intended for use in Audi CEPA and CEPB engines when a crankshaft has been machined to this undersize. The precision manufacturing ensures they fit right into the connecting rod housing, providing the correct clearance for the crankshaft journal. This is crucial for maintaining proper oil pressure and ensuring the longevity of your engine's rotating assembly, especially when rebuilding or modifying.
