This pulley is NLA and therefore I can't find its OD. Can someone tell me the OD of AB4324R? I've found a 3" OD pulley, non-Delco, that will give me a 50% increase in genny RPMs and I want to compare that to what AB4324R would give me. [Reply]   [No Email]

Of course the gennys bearings and bushings and commutator and brushes etc are designed to only run so fast remember!!!!!! If the gennys output isnt satisfactory (at stock pulley size and RPM) you may wanna troubleshoot the system........ John T [Reply]  [No Email]
