This kit is specifically designed to go side by side with our RoushCharger Intercooled Supercharger for any 2007-2008 Ford F150. The supercharger will not work for the 2007-2008 Ford F150 without the Supplemental kit!
The R/C Supplemental Kit is required for compatibility with the visco electric fan assembly. A new larger fan spacer is included to allow mounting of the fan while an updated bracket also provides more precise routing of the wire harness.
