LSA Pulley Spacer

These spacers allow you to convert a standard LSA offset 8 rib pulley to the Innovators West or ATI spacing. This moves the blower pulley one rib forward. Each spacer is precision machined out of 17-4 Stainless Steel and then ground to thickness for zero runout, and comes with longer appropriate hardware.  We can make these for any hub/pulley combo if we have dimensions, but the 2 stocked sizes are for MKII Griptec, and Lingenfelter hubs. MKII Griptec hubs use an M5 bolt, pulley bore/stub is 29.5mm (1.161") with a 1.55" bolt pattern. Lingenfelter hubs use an M4 bolt, pulley bore/stub is 32mm (1.265") with a 42mm bolt pattern.
