King CR4136XP.026 connecting rod bearings for Nissan SR20DE, SR20DET, RB25DET and RB26DETT engines with standard crankshaft. The .026 version is for a standard crankshaft, but with approximately 0.026 millimetres reduced oil clearance. It must therefore not be confused with the 0.25 or 0.5 versions, which are for crankshafts ground undersize.
King XP Series is developed for high-performance engines and motorsport, where ordinary standard bearings are not always sufficient. The bearings are built as trimetal bearings with steel backing, copper/lead bearing material and King’s pMaxBlack surface, providing high load capacity, improved wear resistance and a stable oil film at high RPM and load.
CR4136XP.026 is used for rebuilds, tuning, trackday and motorsport where precise control of bearing clearance is required in Nissan SR20, RB25 and RB26 engines. Correct bearing clearance and crankshaft dimensions should always be verified by measurement during engine assembly.
