For use on supercharged engines to space the oil pump drive gear out away to
clear the supercharger pulley. This billet 6061-T6 aluminum drive mandrel
with stainless mounting hardware is the very best we've seen anywhere.
Designed to be used in conjunction with a 755-3100 reverse mount crossover
mounted alternator and a 755-2000 pulley and 625-3129 spacer. Each mandrel
features stainless belt guides and mounts to any 6 bolt pattern crank pulley and
will accept standard 1" ID X 1" Wide with 1/8" keyway oil pump drive gears.
