Description

Built with enhanced tri-metal, King XP-Series main bearings have a layered copper lead construction, with a nickel plate barrier and lead/tin/copper Babbitt overlay over a steel backing--in an adhesion process that provides superior stability and durability. King's advanced control measures hit a bull's-eye, maintaining wall thickness tolerances far tighter than their competitors: an amazing +/- .0001 in. The XP-Series main bearings are narrowed for large radii crankshafts and feature enlarged, chamfered oil holes with full, 3/4 in., or 1/2 in. grooving for improved oiling. They deliver consistent and reliable performance with a high-load capacity. These race-only Xtreme Performance (XP-Series) Tri-Lecular main bearings are proven track-tough to handle the ground-shaking power of your race engine. Hundreds of sets are available; order the bearings recommended for your vehicle.
