Here is a pic of the Belt Wrap Kit configured for the larger crank pulley shown on an SRT6 with a 185 crank pulley (and a stock SC pulley). There is plenty of wrap eliminating belt slip at the SC . Also, the larger Alternator pulley slows it down to a reasonable speed (larger crank pulleys make the alternator spin up to 19% faster than stock) and eliminates slip there as well. This pic shows a proto alternator pulley, but I am currently having similar production versions of this alternator pulley made for this application (that, like all the other pulleys in the kit, will have a hard-black anodize coating on the belt surface).

Unlike the kit for the 61-65 mm SC pulley which was able to use the original serpentine belt, this kit requires that a new belt (k081177 ) be used.

Cheers,
