Notes regarding using this part on older VMP 8-rib kits:

This will work as a replacement part for old-style VMP 5% and 15% OD kits that used the ATI-918047N balancer with a grind-style FEAD. Replaces VMP-27-8-B. Related part numbers of the old-style 8-rib kits: VMP-SUP020, 50L8RIB, ATI50L5perONLY.

You must remove the 1 mm spacer washer from the Roush style tensioner when using this idler pulley. Your front cover must be well clearanced as this idler now has a lip on it.

The 10-rib version of this idler (VMP-SUI010) is not guaranteed to work on the old-style VMP 10-rib kits as it has not been tested, it may require additional 17 mm ID spacers to line up correctly because that kit requires spacers on the spider bracket.
