MERRY CHRSTMAS EVERYONE

 

From what I gather. Since I have an '11 Rubi automatic which there is no programmer for (err!!) I want to do stock wheels with 315/70/17 Duratracs and a AEV 3.5" premium lift. I guess I will need to do 5:13 or 5:38 to achieve basically what I have stock now with little change. I don't mind a slight fuel mileage drop. I just can't handle loosing 5 mpg from stock. I may need to rethink my set up. Have a blank canvas now. Just trying to put my wish list together. Thanks for the info guys.

 

From what you are planning on doing you can expect a 3 to 4 mpg loss easily. Anytime u lift a vehicle you can always anticipate that for a loss. I lost 2.5 mpg just from leveling and adding 33's to my 2010 tundra when I had it. I'm debating if I want to lift the jeep or not with these gas prices.

 

Auto tranny with 35" or larger tires and front and rear D44's? Get 5.38's!
Auto tranny with 35" or larger tires with a D30 up front and D44 in rear? Get 5.13's
Man tranny with 35's? Get 4.88's

Simple breakdown there. I have 5.38's in my Rubicon and love it! Just wish a tuner would come out for the 11's. I get about 14.5 mpg's overall but its mostly city driving

 

i have a 4" lift, 35" tires and 5.13 gears. i average 15 mpg.

 

Are you running an auto or manual?

 

Do u have a tuner or programmer?

 

auto





40% city, 60% highway, highway averages 70

yes i bought the jeep with the lift, tires and tuner, not sure the brand but i can check

 

Sure there is, the Procal works on all years. It's the tuners like SC which still don't work...yet.

 

How much does the 2dr vs. 4dr play into this? Would I be able to do 4.88 with 37s cuz I'm a 2dr with 6 spd with mixed city highway. Very rare rock crawling, mostly mud in my area.
