What makes King Engine Bearings Track Tough and Street Smart?
King’s HP and XP bearings are specifically engineered to withstand the highest loads and RPMs for today’s top competition engines. King offers the industry’s widest selection of sizes, including special clearance options.
All King Performance bearings feature:
- Tolerance Control: the closest wall tolerances in the industry – Bull’s Eye Tolerance, with all shells matched to .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 and ¾ grooving
- Medium Eccentricity: 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 radii crankshafts
