ACL Bearing Code Breakdown

ACL uses letter codes within its Race Series part numbers to identify the bearing specification. Read these letters together with the size designation at the end of the part number.

CodeMeaningHRace Series bearing specificationHXRace Series specification providing an additional 0.025 mm (0.001 inch) of oil clearance compared with the corresponding H bearingHDRace Series specification with locating-dowel holes for applicable connecting rodsHXDCombines the extra clearance of HX with locating-dowel holes for applicable connecting rods

HD and HXD apply to connecting rod bearings only.

STD identifies standard size. For example, H-STD and HX-STD are both standard-size options, but HX provides additional oil clearance.

Always check the complete part number, engine application, and size designation. Measure the installed bearing clearance during assembly to confirm it meets the requirements of your engine build.
