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

The +0.25mm sizing indicates that these bearings are slightly larger than standard. They are intended for use when the crankshaft journals have been machined down by 0.25mm, often during an engine rebuild to ensure a clean and properly sized surface for the new bearings.

What type of engine is this bearing set best suited for?

These bearings are made with a lead-free composite and are ideal for engines that operate under low to medium loads. They are a bi-metal aluminum material, making them a good choice for many common engine applications rather than extreme performance builds.

Are these bearings environmentally safe?

Yes, these bearings feature a lead-free composite construction, making them an environmentally safe option compared to older bearing materials.

Product Details

What you get here is a set of connecting rod bearings from King Engine Bearings, specifically sized at +0.25mm. These bearings are designed for a range of VW and Audi engines, including those found in models like the Volkswagen Golf and Jetta, as well as the Audi 4000. They are a bi-metal aluminum material, built with a lead-free composite that makes them environmentally safe and well-suited for engines that don't see extremely heavy loads.

King has been specializing in bearings since 1960, focusing on making them as high quality as possible. This particular set uses an aluminum material with a lead-free composite, which is a solid option for many common engine builds. The +0.25mm sizing means these are intended for engines that have already been machined to that specification, often during a rebuild to clean up the crankshaft journals.
