Product Description

The King Engine Bearings MB5013XPSTDX main bearing set is engineered for high-performance GM LS-series V8 engines ranging from 4.8L to 6.2L. Built using King's XP-Series tri-metal construction with a hardened pMaxBlack™ overlay, these bearings are designed to withstand extreme cylinder pressures, elevated RPM, and high-load operation commonly found in performance street, track, and racing applications.

The STDX specification provides approximately +0.001" additional oil clearance compared to standard-size bearings, making this set ideal for engines using forged crankshafts, higher viscosity oils, or operating under sustained high temperatures. Precision manufacturing ensures consistent wall thickness and reliable oil film stability, helping extend crankshaft life and improve durability in demanding LS engine builds.
