Are you having belt slip issues with your supercharged HEMI engine? MMX has the solution for you! This tensioner puts out 20+ LBS more tension than the factory belt tensioner! This will prevent your blower drive belt from slipping due to the increased load demand that superchargers require. We have outfitted this tensioner with one of our in-house designed double bearing idler pulleys with Timken bearings.

The best part is, MMX has designed this tensioner to require no belt length change! That’s right, simply remove your existing belt tensioner, and bolt on the MMX High Boost Tensioner into its place without changing any other components! Pick yours up today for only $249.95!
