Product Description

Performance Engineered for a First-Place Finish

What makes King Engine Bearings track tough and street smart?

King HP and XP lines are specifically engineered to withstand the highest loads and RPMs generated by today’s top competition engines. All King Performance Engine Bearings feature:

Performance Car
  • “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.

King offers a wide selection of sizes for Subaru engines, including special clearance options. With more choices than ever, you’ll find the right King HP and XP High Performance Engine Bearings for your most demanding applications.

  HP Bearings XP Bearings
  • High-load, short-duration racing such as drag racing, Auto X etc.
  • Medium-load, long-duration racing such as road course racing.
  • High-load, long-duration racing such as road course endurance racing, top speed challenge etc.
  • Bi-metal aluminum silicon alloy featuring fine micro-bore finish
  • Enhanced tri-metal copper lead construction with nickel barrier and SecureBond adhesion
  • 0.015" thick top layer for superior macro particle embedability and conformability
  • 40 Vickers hardness to resist overlay migration and extrusion
  • 450°F heat threshold for superior protection against friction and overheating
  • Mains are 3/4 grooved for improved oiling to the rod journals
  • 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
