King Engine Bearings has introduced new rod and main bearings for Acura/Honda engines in its XP Engine Bearings line.
The enhanced tri-metal, copper lead construction with nickel barrier of the XP Bearings features King's proprietary SecureBond advanced adhesion process. This unique process provides superior stability between the top and intermediate layers.
King XP Bearings are available for Acura/Honda applications, including rod bearings (CR 439XP) and main bearings (MB5259XP) for B17, B18A, B18B engines; rod bearings (CR4046XP) and main bearings (MB5568XP) for D16 engines; and rod bearings (CR4287XP) and main bearings (MB5259XP) for B18C engines. All new XP parts are available in STDX, STD, 001 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 ¾ 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.
