You might wanna skip over the 3.92s and go to 4.56s. Hit up Duane at 3rd strike (Vendor here) and order em up. Whats currently in your truck now? Most guys when they make the jump they go to the 4.56s esp if a lift is planned.

i had 4.56's in my Dakota R/T obviously no lift or big tires so i just automatically compare my truck to that. i think the biggest tire im planning on going with is a 35/12.50 so 4.56 is probably the way to go for sure? btw im not sure what my truck came with stock for gearing.

I'm willing to bet that you have 3.55s. hop under the truck - there is a sticker on the axle. :D

I have a set of 4.56's and an Auburn LSD in my back seat just waiting to be installed! If all goes well they should be in by tomorrow!

Just got my 4:56's in and they are sweet. I think there is some grinding needed on housing though to get this large of a ring to fit in the housing.

Yeah if I was changing gears I'd be running no less than a 4.56.

God I bet the launch power is incredible.

Nope....they called me up saying they wanted the master install kit to do the installation so I got the master kit from third strike and dropped it off again this morning(and then biked my way to work)

Well here I am thinking everything is going smooth and I get a call from them around 4pm telling me they couldn't get to my truck since a bunch of commercial vehicles came in and they take priority. He said he'd have time next week and told him that's not good enough since I'm moving cross country on the first and need to have the gears broken in.

So now I'm going to have to wait until I get to Charleston and trust the job to people I don't even know(this installer was recommended to me by a bunch of people)


Needless to say I'm not very happy right now...

Verified my mechanic did have to grind on housing to fit 4.56 in rear end. No mods needed in the front. Also do you guys know what front end is considered on 09 1500 is it a Chrysler 8 or 8.25? Looking for differential cover.
