Alright guys, so I have a 8.5 in rear end in my 1500. I have an auburn locker and 3.73 gears I have been looking for a rear diff cover that has GM Performace or GM race or something. I've seen a few and haven't found any.


Also I've seen a GM Performace CaI for these trucks but can't find it and I'm getting tired of my FIPK KnN because I can't drive in the rain.

 

Never seen one with a GM logo on it but TA performance makes them so maybe they can do it for you.

As far as the CAI from GM performance parts. Good luck finding one most everything has been discontinued as there basically over the 10 year mark on the GMT800 platforum.

You could do an Airaid Jr kit with a factory style box that is enclosed.
