The VMP 90mm idler pulley uses a factory size and brand NSK bearing, when the
proper sized bearing is used the need for double beairngs is eliminated. Use
this idler to take up belt slack and get better wrap with smaller supercharger
pulleys. Can be used with 2.6", 2.7" or 2.8" super charger pulleys
on GT500. Also used with Roush M90 and P51 TVS blowers when installing a smaller
SC pulley. Will fit other applications that require a idler with 17mm bore.
Factory bolt is re-used.
