Supercharger Installation Kit
2003-2004 Mercury Marauder and Select Mustang Applications
8-Rib Supercharger Drive
The components in this kit are offered under a single part number to complement the supercharger conversion parts provided by other suppliers.
These parts, when used in conjunction with the appropriate supercharger and brackets, will facilitate the installation of the Cobra-style Eaton supercharger on the 4V Mercury Marauder or Mach 1 application. The kit includes our billet crank pulley hub with fasteners, your choice of crank pulley ring (with fasteners), and a two-piece supercharger pulley kit with the ring size of your choice.
This kit does not include all of the parts necessary for this conversion. It is up to the buyer to source the main components for the kit, including the supercharger, brackets, and miscellaneous components. Modifications are required. An excellent resource detailing the parts necessary for this conversion is available here:

Our crank pulley hub is manufactured to fit the typical balancer originally used in Mach 1 and Marauder applications. This balancer can be identified by the large recess in the center with (3) M10 threaded bolt holes, and a raised register in the center of the recess for the balancer bolt. No crank pulley hub is available to fit the less common version of the balancer used in select Modular Ford applications. And unlike the knock-offs of this kit offered by another supplier, the crank pulley hub included in this kit is specially configured to mate properly with the Marauder's (and Mach 1's) balancer - it is not simply a repurposed Cobra crank pulley hub. This conversion crank hub will fit tightly over the raised register in the center of the balancer, resulting in virtually no run-out.
Fitment of crank pulley rings larger than 10.0" is unconfirmed in these applications.
