Product Overview

Successful race engine builders are constantly pushing the limits of load capacity to new levels. Race bearings today inevitably need to match these demands with more competitive bearings. At King Racing we met the challenge with the XP high performance bearings series.

The 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. For more on King Racing technologies visit TechLab

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

We offer the industry’s widest selection of sizes, including special clearance options. With more choices than ever, you’ll find the right King High Performance Engine Bearings for your most demanding applications.

*King XP Bearings Features*

*Applications*
• High-load, long-duration racing such as circle track, off-road, off-shore, and others that require steel crankshafts

*Construction*
Enhanced tri-metal copper lead construction with nickel barrier and SecureBond adhesion

*Features*
• 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

• PMaxBlack for Superior Load Capacity
• Radialock for Optimal Crush Height
• Tri-metal Copper Based Material

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.

King XP-Series rod bearings feature advanced metallurgical and geometric technologies that meet extreme performance loads. They were developed for all performance applications that use forged steel aftermarket crankshafts and produce high loads for extended periods.

King focuses on one product—bearings—and nothing else. Their innovative race-only Xtreme Performance Max Black Tri-Metal rod bearings have a 24 percent stronger overlay and 17 percent more fatigue strength by using a micro process called SecureBond. Built with enhanced tri-metal, King XP-Series rod bearings layer copper-lead construction with a nickel plate barrier and a lead/tin/copper Babbitt overlay over a steel backing in an adhesion process that provides superior stability and durability. King's advanced control measures hit a bull's-eye, maintaining wall thickness tolerances far tighter than their competitors—at an amazing +/- .0001 in.! XP-Series rod bearings are narrowed on the crank cheek side with increased crush height for improved bearing-to-bore contact, heat transfer, and reduced spin potential in high-rpm applications.
