ATI 918854 Supercharger Pulley 6 bolt mod kit – LSA Only

Let’s face it, the evolution of the 2650 blowers is starting to push the limits of your typical LSA components. The lower pulley ring is one of these items subject to failure. After Rick Crawford posted about performing this modification on his own car, we were asked to come up with a solution for our 10″ pulleys. This mod will utilize the 3 extra a/c ring mounting bolts to help keep the supercharger pulley seated and minimize distorting.  (This only works on the DMS 10” lower or any other pulley ring that does not have the relief pockets)

Only works with ATI part number 918854. We’re working on a solution for the LT4’s.
