What does '.25 Oversize' mean for these bearings?

'.25 Oversize' means these bearings are designed to fit crankshaft journals that have been machined down by 0.010 inches (0.25mm). This is common during engine rebuilds when the original journals have wear or damage.

What is the pmax Black tri-metal material?

The pmax Black tri-metal is King Engine Bearings' racing line material. It's a three-layer composite designed for higher load capacity and improved wear resistance compared to standard bearings, making it suitable for performance applications.

Do these bearings come with installation instructions?

While installation instructions are not included with this bearing set, it is critical to follow the specific service manual for your vehicle's VR6 2.8L engine. Proper installation, including correct torque specifications and oil clearances, is essential for engine health.

About this part

Product Details

This is a set of 7 pairs of King Engine Bearings main bearings, sized .25 inch oversize. These are the pmax Black racing line bearings, which use a tri-metal construction for improved performance in demanding applications. They are designed to fit a wide range of Volkswagen VR6 2.8L engines, as well as many Audi models from the early 90s through to the early 2010s.

The pmax Black tri-metal material is a step up from standard bearings, offering better load-carrying capacity and durability, especially when you're pushing your engine harder. Because these bearings are .25 inch oversize, they are intended for use when the crankshaft journals have been machined down to match this size during an engine rebuild. This ensures a proper fit and oil clearance, which is critical for engine longevity and performance.

When rebuilding your VR6 engine, especially if you're aiming for improved performance or are dealing with worn components, a well-matched set of main bearings like these is essential. Make sure to verify your crankshaft journal size before ordering, as these are specifically for a .25 inch undersize condition.
