The enhanced tri-metal, copper lead construction with nickel barrier of the XP Bearings features King's proprietary SecureBond advanced adhesion process which provides superior stability between the top and intermediate layers.
King XP Bearings are available for Nissan applications, including rod bearings (CR 4136XP - 17mm rod width) and main bearings (MB 5243XP) for SR20DE, SR20DET non-GTIR engines. These XP parts are available in STDX, STD, and 010. Extended sizes may become available in the future.
The XP Bearings have a .0005" enhanced performance Babbitt overlay which provides as much as 30 percent greater load capacity than traditional bearings. They are suitable for operating temperatures of up to 350 degrees Fahrenheit.
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 and ½ grooving. In addition, most rod bearings are available with or without dowel holes. 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. In addition to main and rod bearings, King also offers camshaft bearings and thrust washers.
King Engine Bearings is known for its extensive line of high performance engine bearings for circle track, drag racing, monster trucks, tractor pulls, off-road and off-shore racing applications.
