ooks like the P/N for Gatorback is 4081369. That should be the 8 Rib 137.35" belt for Dual Alternators. I would check with your auto parts store though!
Tensioner P/N varies, but here is one: 305257

Personally, I haven't had as much luck with the Gatorback as with the Gates belts. Don't want to start a "which belt is better" conflict... just sharing my own personal experience with my two 7.3's.

Again not to start a war, the gatorback belt on mine has not caused me any problems. Its been on it since I got the truck 30,000 miles ago. Only thing ive noticed is it has skipped back a couple notches. It has a couple nicks in it, but for the most part is doing fine. Of course now that I said that its going to break in the next two weeks with my luck lol.

Gatorback has been the best I've ever used. It has been absolutely great on my truck and has been through rain, mud, dust and rivers and has yet to slip or make any noise at all.
I wish I could help you with part numbers since I got a new tensioner and idler pulleys when I got my belt last time (I write all the part numbers down), but I'm on deployment and don't have access to my maintenance ledger. The part number and length that woodnthings listed sounds right, but don't quote me. I think I got all my stuff from RockAuto Auto Parts (they also post OEM part numbers for their stuff too). I would double check with your dealer to make sure you get the right tensioner for your year as there are several that are similar with only small differences (width of the pulley and ribbed vs. smooth).
Sorry I couldn' t be of more help.
