6.0L / 6.4L Ford Power Stroke MAHLE Clevite Racing H Series Main Bearings

6.0L / 6.4L Ford Power Stroke MAHLE Clevite Racing H Series Main Bearings Clevite H-Series Main Bearings Clevite H-Series main bearings were developed primarily for NASCAR racing, but are well suited to other types of competition engines as well. They're especially good for engines that run at medium-to-high revs. They have steel backings with carefully selected overlays and a high crush factor, plus a medium level of eccentricity. H-Series bearings have enlarged chamfers at the sides for greater crank-fillet clearance and are made without flash plating for better seating. They are also available an extra 0.001" of oil clearance. Cross Reference: • 3C3Z6D309AA • 3C3Z6D309BA • 3C3Z6D309CA • 3C3Z6D309DA• 1843028C93
