Besides the Dayco pulley, a Gates 36100 Belt Tensioner Pulley. - Steel 75mm 6 Rib steel with 17mm bearing bore is also available for use with the Gates 38131 Belt Tensioner Assembly.

If you just can't stop there and feel the need for different idler pullies; Gates 38042 Idler Pulley. Steel 90mm Smooth/Backside, 17mm Bearing Bore with 10mm adapter (not used, the radix standoff replaces it).

 

the vortech uses stock tensioner position, not a separate bracket like the radix, so is there anyway to get a heavy duty one for a stock location bolt up? i checked with Katech, they make hd tensioner for high rpm apps for the truck, but says not for use with supercharged engines?
