Looking to go to 4.88's from 3.73's

[Kingx1]

Ok so I got a 6" lift on 35's and as of right now I have stock 3.73 gears. I lost a lot of get up and go with the lift and tires with the stock gear ratio. I'm doing some towing of a camper recently too so I really need to switch them out. In feel like I'm wasting more gas on top of it due to having to mash the gas harder to get going. Can anyone point me in the right direction as far as a good full kit that I can supply a shop with? I don't wanna put junk in my truck that could break prematurely.


By the way its a 2004 Yukon Xl 2500 with a 14 bolt rear

Wow no help yet huh? Are you 4WD? I'm just beginning my research in going from 3.71 to something a bit higher but wondering if 4.11 is too much. I have been looking though and although they make a rear set at 3.90 I can't find a front set that match; they seem to go from 3.73 to 4.11. I'm running 305/30 26's and want a better launch but don't want to sacrifice highway driving and towing. Also looking into whether or not it's something I want to tackle myself or have a shop do it. Motive Gear and Yukon have come up in my searches so far. Summit racing has a good selection as well as www.ringpinion.com.
