VMP 10-Rib Upgrade kit for '20+ Predator 5.2 L with AC - 10% OD Upgrade kits do not include some of the universal components that may already be present, such as upgraded belt tensioners or wrap brackets. This version of the VMP 10-rib kit is for '20+ Predator 5.2 L engines with the factory AC compressor. Supercharger pulleys sold separately. VMP-Magnuson Predator superchargers or stock superchargers with the VMP M18 Hub must use a hub spacer and longer bolts. If you are having your own pulleys made the belt alignment is +1 backward and +1 forward. This kit also works with front covers that have already been ground.
