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

Specifications

Crankshaft Main Bearings BMW M40, M42, M43 1.6L, 1.8L

Built with enhanced tri-metal, King XP-Series main bearings have a layered copper lead construction, with a nickel plate barrier and 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: an amazing +/- .0001 in. The XP-Series main bearings are narrowed for large radii crankshafts and feature enlarged, chamfered oil holes with full, 3/4 in., or 1/2 in. grooving for improved oiling. They deliver consistent and reliable performance with a high-load capacity. These race-only Xtreme Performance (XP-Series) Tri-Lecular main bearings are proven track-tough to handle the ground-shaking power of your race engine. Hundreds of sets are available; order the bearings recommended for your vehicle.
