The King XP Series is developed for engines subjected to high loads and prolonged hard use. The bearings are manufactured as tri-metal bearings with a copper/lead bearing material and King's pMaxBlack surface treatment, providing high load capacity, excellent wear resistance and a stable oil film under demanding operating conditions.
MB7039XP-STD fits BMW M20 and M50 engines in 2.0L, 2.5L and 2.7L versions. The set is supplied in STD size for a standard crankshaft and is suitable for classic BMW restorations, tuning, track use and motorsport.
