King XP series is a line of bearings with advanced metallurgical and geometric technologies that meet extreme performance loads. It was developed for all performance applications that use forged steel aftermarket crankshafts and produce high loads for extended periods.

King Racing’s XP series features pMax Black™, a unique tri-metal structure that is 24% harder than any other conventional tri-metal race bearing. pMax Black™ together with the XP geometric features are the ideal combination for performance racing.

If you’re rebuilding your engine with forged internals, make sure you top off your investment with a set of King Main Bearings. 
 
Features:
- pMax Black™ featuring a unique tri-metal structure
- 15% - 30% greater load capacity than traditional bearings
- The SecureBond unique adhesion process, for superior stability between the top and intermediate layers
- 0.0005” metallurgically enhanced and hardened performance overlay withstands greater loads and better resists surface fatigue
- Mains are 1/2 grooved for uncompromised lower shell load capacity
 
Tech Features:
- “Bull’s Eye Tolerance”. King engine bearings have the closest wall tolerances in the industry, with all shells matched to 0.0001”.
- Increased Height. Greater rod bearing height improves bearing-to-bore contact/heat transfer and reduces spin potential at high RPM.
- Improved Oiling. Mains feature enlarged, chamfered oil holes.
- Medium Eccentricity. This enables optimum load distribution and improved oiling.
- Dowel Holes. Most rod bearings are available with or without dowel holes.
- Narrowed Design. Mains and rods are narrowed for large-radius crankshafts.
- High-load, long-duration racing such as circle track, off-road, off-shore, and others that require steel crankshafts
- 15% – 30% greater load capacity than traditional bearings
- The SecureBond unique adhesion process, for superior stability between the top and intermediate layers
- 0.0005” metallurgically enhanced and hardened performance overlay withstands greater loads and better resists surface fatigue
- Mains are 1/2 grooved for uncompromised lower shell load capacity
