not much dude.. ive got 11" on my 2wd and get bout 15.5-17 in town. ive got a programmer, exhaust, intake and 4.10s on 37s. i dont race it around and im pretty light on the pedal. id go with the 7" dude. youll wish you had later.


heres a pic of when i first put the 7" and 35s on bout 48hrs after i bought the truck.

word, mileage between 33s n 35s would be minimal...a regear wouldnt be that expensive either beings its only 1 axle

the tyres calculator say i need 3.97 ratio for a 35 in tire...so would i want to run 3.73 or 4.10? and also would 35s fit with about 5 inches of lift? (3" spindle and 2" spacers)

35s on 5" would be realllly tight. id venture to say 5" wouldnt be enough. youd rub everywhere. and really that 5" isnt gonna be a true 5" cause the spacers arent going to give you an actual 2" of lift. youll probably get 1-1.25" to be honest. if you got 35s id say 4.10s would be sufficient. id probably even get 4.10s with a good size 33 since thats about all youll truly be able to run with around 4-5" of lift.

you gotta buy the gears then you got labor on top of that. if you decide to get the master install kit then itll be a bit more. id say with parts maybe $350? i was quoted $350 for 4.88 and install for mine through desert rat.

350 is cheap! jump on that deal. just the kit and bearing kit is around $250. most places charge $500+ parts and labor, but its worth it!!!

if its a 4wd then i can understand 500 in labor alone. i can get the 4.88s and install kit for like 250 and then install on top of that they said 300. if i dont get the master install kit then itd be like 350 out the door supposedly. dunno if ill need the install kit since ive only got 15k on my current setup.

Yep go with the 7" kit if you're smart. I've got the coil spacers and 3" BL on mine with 33's and I trying to figure out a way to go bigger already. I'm thinking of ditching the spacers and putting a 4" spindle up front and a 2 or 3" block in the back. But then I'd have to buy new tires.

I get 15.2 with 10" lift 35" tires and 4.56 gears and Im not light on the pedal.

Id imagine 16mpg avg if I was light on the gas


Edit: My lift kit might be for sale if any of you 2wd guys are interested PM me.

el semental, you mean you don't know your rear gear ratio?

And I'm surprised that 33's would get smilar gas mileage to 35's...aren't the stockers something like 32" on a 4x4? If they get similar gas mileage, what are the advantages to running 33's other than initial cost (of lift and tires)?

My best tank with 90% Highway was 18mpg. 5" lift, 33" BFGs & 3.73. Not sure about city mileage, I really don't care because it's going to suck know matter what!
