I was wondering if anyone could point me in the diirection of a reputable shop in the NJ,DE,PA, and even MD area that can do a 4.56 gear swap on my 2003 Dodge RAM 2500? The closer to south jersey the better. I have been quoted two prices of $1000-$1500 for the labor alone NO PARTS, for the front and rear. I thought this was kinda steep after reading some of the chats about people getting everything done including parts and servicing after break in for around $1000, but maybe I am wrong. I was hoping a I could save a little money buying the gears and install kits myself and having a shop install them, I am more of a back yard mechanic, and after hearing some of the stories on here about whining and grinding rears, I think I'll stick with the experts for this. Also I have done some research and can only locate 4.56's for the 10.5" AAM rear in my truck, does anyone know if there is a 4.88 ring and pinion for my application? Thanks for your help HTC.com ROCKS!!

I had my 4.56 gears installed by Wayne at Heads Up Performance. Excellent job no complaints at all.
I have a 4X4 and he did the front and back differentials. He's one of the few places that has experience with swapping the gears on the front diff.

Thanks!! I'll give him a call first thing Fri. morning!

hey how much did you get a quote from the shop in nj 04hemiquad told you about

with and or w/o gears i need a shop too. I have 456's with tru trac setting here and my b day is comming up and my girl said she would get them installed for me since im broke.

I supplied the parts (gears and master install kits) when I had it done by Wayne and he had no problem with that.

4.56's is all they offer for the 10.5 rear end,no 4.88's

Just got off the phone with Wayne at Heads Up. Labor: $400 for back rear and $500 for the front rear.
