The bearings are manufactured as tri-metal bearings with copper/lead bearing material and King's pMaxBlack surface treatment, providing high load capacity, good wear resistance and a stable oil film under demanding use.
MB5243XP-STD fits Nissan SR20DE and SR20DET engines and is relevant for classic Nissan rebuilds, tuning, track use, drifting and motorsport.
