King XP Coated LS Main Bearings +.001" Extra Clearance MB5013XPCSTDX
pMaxKote Coated Xtreme Performance Tri-Metal Main Bearing Set for LS 4.8L 5.3L 5.7L 6.0L 6.2L Engines
Give your LS engine a stronger foundation with King XP Coated Main Bearings, part number MB5013XPCSTDX. Built for demanding naturally aspirated, high-RPM, and boosted combinations, this Xtreme Performance bearing set features King’s advanced tri-metal construction, factory-applied pMaxKote nano-composite coating, enlarged chamfered oil holes, and +.001" additional oil clearance. It is a premium main bearing option for stock or aftermarket crankshafts where the engine combination calls for increased clearance and enhanced protection under sustained performance loads.
Key Features & Benefits
- + .001" Additional Oil Clearance: This King XP main bearing set is built with +.001" extra oil clearance for engine combinations that require more clearance than a standard-size bearing set provides. It is well suited for performance, high-RPM, boosted, and high-load LS builds where the crankshaft, oiling system, and intended operating conditions call for a larger bearing clearance target.
- Factory-Applied pMaxKote Nano-Composite Coating: King’s pMaxKote coating is factory applied to improve seizure resistance, cavitation resistance, wear resistance, and protection during oil-starvation conditions. The coating is engineered to add protection without adding thickness, helping maintain the bearing geometry required for a properly measured performance engine assembly.
- Xtreme Performance Max Black Tri-Metal Construction: King XP-Series bearings use enhanced tri-metal construction with a steel backing, copper-lead layers, nickel barrier, and lead/tin/copper babbitt overlay. The SecureBond micro-process provides a 24 percent stronger overlay and 17 percent greater fatigue strength to support engines exposed to elevated loads for extended periods.
- Enhanced Oiling and Large-Radius Crankshaft Clearance: These XP-Series main bearings are narrowed for large-radius crankshafts and feature enlarged, chamfered oil holes with 3/4 grooving for improved oiling. This makes them a strong choice for LS builds using performance crankshafts or combinations where improved oil delivery and crankshaft fillet clearance are important considerations.
- Precision-Controlled Wall Thickness: King maintains wall thickness tolerances of +/- .0001" through advanced manufacturing controls. This level of consistency gives engine builders a dependable performance bearing foundation when measuring and setting main bearing clearance on stock-crank rebuilds, aftermarket rotating assemblies, boosted street builds, or dedicated racing engines.
