Why Choose King XP Series Racing Main Bearings?
King Engine Bearings developed its XP Series for applications where conventional replacement bearings may not offer the required performance characteristics.
The combination of tri-metal copper-lead construction, precision-controlled bearing geometry and advanced overlay technology makes these bearings suitable for professionally prepared performance engines.
Key Features and Benefits
1. Advanced pMaxBlack™ Technology
King’s proprietary pMaxBlack™ overlay uses a nano-scale hardening process to provide enhanced bearing load capacity for demanding engine operation.
2. High-Performance Tri-Metal Construction
A durable steel backing and copper-based bearing construction provide the strength and fatigue resistance required for performance engine applications.
3. Precision Oil Clearance Options
The 0.026mm additional-clearance version allows engine builders to select a suitable bearing specification according to actual crankshaft and housing measurements.
4. U-Groove™ Oil Distribution
King’s U-Groove™ design uses an optimised oil-groove profile to improve the available bearing load surface while maintaining lubrication flow.
5. Radialock™ Bearing Retention
Optimised bearing crush characteristics support correct bearing seating and heat transfer between the bearing shells and engine housing.
6. Eccentrix™ Bearing Geometry
Engineered bearing eccentricity supports hydrodynamic oil-film formation and lubrication under operating loads.
7. Bull’s Eye™ Manufacturing Tolerances
Strict bearing-wall thickness tolerances help engine builders achieve consistent, predictable clearances across the bearing set.
Volkswagen VR6 Engine Applications
These King XP Series main bearings are listed for selected Volkswagen VR6 engine applications, including 2.8L and 3.2L configurations.
Relevant applications within the MB7089XP bearing family include selected Volkswagen Golf, Corrado and other Volkswagen and Audi VR6-powered models.
Compatibility must be confirmed using the exact engine code and crankshaft measurements. Not every VR6 variant uses identical bearing specifications.

Choosing the Correct Bearing Size
Selecting the correct main bearing size is essential when rebuilding or upgrading a Volkswagen VR6 engine.
The MB7089XP.026 is the 0.026mm additional-clearance option. It must not be confused with the 0.25mm or 0.50mm undersize variants, which are intended for different crankshaft journal specifications.
Before installation, have a qualified engine builder check:
- Crankshaft main journal diameters
- Engine block main bearing housing dimensions
- Required bearing oil clearances
- Crankshaft condition and journal finish
- Compatibility with the engine’s main bearing housing
Important: Bearing selection should always be based on measured dimensions and the manufacturer’s technical data rather than vehicle model alone.
