King Racing – New design for Nissan Applications

As race engines evolve, and become more and more powerful, the need for engine bearings that can withstand the increasingly higher load capacity on these higher power engines is needed. Focusing on Sport compact applications, King Racing has developed the following features that ensure their XP series rod and main bearings can perform under the highest stress and maintain the level of durability and performance they are known for. As part of the sport compact range expansion, King is offering new items for Nissan including the Nissan GTR VR38DETT

pMAX Black™ – This unique tri-metal bearing structure was developed to meet the ongoing demand for increased engine bearing load capacity. The intermediate layer uses a copper based alloy with 4.5% tin for added strength that is the strongest in the industry, at 115 HV. This gives the bearing a load capacity of 17,000 psi in the intermediate! The overlay is also 24% stronger because of a 5% copper alloy with a fatigue resistance of 10,200 psi, 17% more than a standard bearing. King’s SecureBond™ etching process also improves the multi-layer adhesion and structural integrity of the bearing. 

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
