King XP engine bearings were developed for high load high performance engines. King XP bearings are easily recognizable due to their distinctive deep dark color gained from their proprietary surface hardening treatment. The hardened surface provides a significant increase (about 17%) in its load carrying capacity. King engine bearings have the closest wall tolerances in the industry, with all shells matched to 0.0001''. Greater rod bearing height improves bearing-to-bore contact/heat transfer and reduces spin potential at high RPM. Mains feature enlarged, chamfered oil holes.
  • High-load, long-duration racing such as circle track, off-road, off-shore, and others that require steel crankshafts.
  • Enhanced tri-metal copper lead construction with nickel barrier and SecureBond adhesion.
  • 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
