What does the 0.25mm undersize mean for these bearings?

The 0.25mm undersize designation means these bearings are intended for use on a crankshaft that has been machined down by 0.25mm. This is a common practice during engine rebuilding to restore proper oil clearance when the original crankshaft journals are worn or have been ground undersize.

What is the Tri-M+ babbitt overlay?

Tri-M+ is an enhanced babbitt overlay developed by King Engine Bearings. It's designed to provide improved performance and durability, particularly in medium-load engine conditions, by offering better resistance to wear and fatigue.

Are these bearings sold individually or as a set?

This product is a set of connecting rod bearings. Typically, a set includes enough bearings for all the connecting rods in the specified engine.

About this part

Product Details

If you're rebuilding the engine in your 1997-2004 Volkswagen Jetta, especially one with the ABL, AEY, AGR, AHH, or AHU 1.9L engine, you'll need a solid set of connecting rod bearings. King Engine Bearings has been specializing in these critical components since 1960, focusing on supplying well-built bearings for a wide range of applications.

This set features a tri-metal copper-based material with an enhanced babbitt overlay, known as Tri-M+, which is a popular choice for medium-load engines. These bearings are 0.25mm undersize, meaning they are designed to be used on a crankshaft that has been machined down by that amount to restore proper clearances. King's focus on bearing specialization means you're getting a part built with a clear objective: to perform reliably in your engine.
