Build your LS bottom end with the King MB5013XP standard size main bearing set. Designed for the listed LS-based engines, these XP-Series performance bearings can be used with stock or aftermarket crankshafts. Their enhanced tri-metal construction combines a steel backing, copper-lead bearing material, a nickel barrier and a lead/tin/copper babbitt overlay for stability and durability in demanding engine applications. Controlled wall thickness tolerances of ± .0001" support precise bearing selection, while a narrowed profile accommodates large-radius crankshafts. Enlarged, chamfered oil holes and 3/4 grooving improve oiling, making this King XP main bearing set suitable for compatible performance rebuilds and race engine assemblies.
