King Engine Bearings has released its new application guide for the company’s HP and XP high performance engine bearings. King manufactures a large selection of bearings engineered for specific applications, including: circle track, drag racing, monster trucks, off-road racing, tractor pulls, sprint cars and off-shore racing.
The new application guide includes information on the company’s expanded line of HP and XP main and rod bearings that are available for Chevrolet, Chrysler and Ford vehicles, as well as, several custom performance applications. The company has also released new XP main and rod bearings for Acura/Honda, Mitsubishi, Nissan, Subaru and Toyota vehicles.
In addition, the company has introduced a new simplified performance numbering system that retains the "core number" from King’s OEM replacement bearing and changes the suffix to reflect material and features making it easier for engine builders to select the right bearing.
The enhanced tri-metal, copper lead construction with nickel barrier of the XP bearings features King’s proprietary SecureBond advanced adhesion process that provides superior stability between the top and intermediate layers. The 0.0005" metallurgically enhanced and hardened performance overlay withstands greater loads and better resists surface fatigue. XP bearings are ideal for high load, long duration racing such as circle track, off-road, and off-shore in engines using steel crankshafts. XP main bearing sets are 1/2 grooved for uncompromised lower shell load capacity.
Made of bi-metal, aluminum silicon alloy, the HP bearings feature a 40 Vickers hardness that resists traditional overlay migration and extrusion making it ideal for the demands of high load, short duration race environments such as drag racing, tractor pulls and monster trucks. It is also suitable for medium-load, long duration racing such as circle track engines using nodular cast iron crankshafts. HP main bearing sets are 3/4 grooved for improved oiling to the rod journals.
All King performance bearings feature greater rod bearing height that improves bearing to bore contact/heat transfer and reduces spin potential at high RPMs. Main bearings feature enlarged, chamfered oil holes. Medium eccentricity enables optimum load distribution and improved oiling. In addition, most rod bearings are available with or without dowel holes. According to the company, King bearings feature the closest wall tolerances in the industry (Bull’s Eye Tolerance), with all shells matched to .0001". Main and rod bearings are narrowed for large radii crankshafts.
