What does the 0.25mm undersize mean for these bearings?

The 0.25mm undersize designation means these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilds to ensure proper clearance and fit with worn or reconditioned crankshafts.

What is Silvercore technology?

Silvercore is a technology developed by King Engine Bearings that utilizes a tri-metal copper-based material. It's specifically designed to provide enhanced strength and durability, allowing the bearings to withstand extreme load conditions within the engine.

Are these bearings compatible with all Audi A4 models?

This bearing set fits many Audi A4 models, but it's important to verify fitment for your specific year and trim. The fitment data indicates compatibility with a broad range of A4 Quattro and standard A4 models from 2009 through 2020, excluding some specific years.
