You are looking at King Bearings pMaxBlack (XP) Performance Rod Bearings without the pMaxKote (XPC) for the Mitsubishi EVO X.
Click here for the pMaxKote(XPC) line of Performance Coated Rod Bearings for the Mitsubishi EVO X. For a better understanding of the differences, please read below.
pMaxBlack™ is a surface hardened lead tin copper overlay that is electroplated onto a copper alloy substrate making up the third layer of a King XP bearing. pMaxBlack™ also has additional copper content, when compared to regular tri-metal bearing overlays, increasing the fatigue strength to handle loads up to 10,200 psi.
pMaxKote™ is a factory applied nano composite polymer coating formulated especially for pMaxBlack™ overlays. pMaxKote™ provides excellent wear and cavitation resistance while protecting bearing surfaces during periods of oil starvation and minimum oil film thickness. pMaxKote™ is applied with no added wall thickness therefore not altering oil clearances.
*STD bearings offer factory OEM clearance
STDX bearings are for extra clearance - use STDX bearings in order to get .001" (0.026mm) extra clearance. STDX bearing shells are .0005" thinner than STD size.
.26 - .001" aka .026 bearings are for tighter clearance - use in order to get .001" (0.026mm) tighter clearance. .001" / .026 bearing shells are .0005" thicker than STD size.
.001" is an inch size while .026mm is a metric size, but both are essentially the same.
