i have a 07 1500 with 3.92 gears. thinking about a body lift and some 35s. was wondering what mpg i would be getting with the 3.92? i now have 33s and getting 12 to 13 mpg. this is mostly short trips here and there. on a long trip i will get around 15mpg. thanks.

well i can squeeze out 18 mpg with a stockish truck (mds ON) on the highway and around 14 mpg in the city. ill be going up to 34 inch terra grapplers i think

im also interested in the responses

i have the mds turned off. mine did not come as much when i put the 33s on it. plus i hate the sound when the mds was on so i turned it off.

i just have a hooker aerochamber muffler and i dont mind when mds is on...the muffler gives it a very bass tone...it drones but for some reason i just dont mind it...plus it acually works so i dont mind at all...

i have 33's stock and it comes on often enough...i can acually get up to highway speed using mds only...but 4.56 gears will help with mds ALOT i think so im definitally going to try it out this spring!!

i am hoping that 4.56 gears will change that

35" toyo mt's...4.56 gears...auto tranny: 10ish in town, 12ish on Hwy.

Haven't recalibrated the speedo yet, but when comparing to the gps, it's only reads about 5% slow, which would add about .5mpg to those numbers. A little less skinny pedal would probably help even more.

I'm getting about 10-11 mpg in town. I haven't really driven on the highway a whole lot since I put them on.

3" body lift, 2" level, 35" tires. 12-13 mpg city, 15-16 highway. More if I keep it under 65.

 

[Hemi5.7L4x4]

I get about 13 mpg all the time. I have 35 toyo m/t's and 4.56 gears.

 

[sighless]

13mpg max.. on a 6 hour trip.. cruise set at speed limit and no stopping..

this is hand calculated.. on dick cepek mud country's 35x12.50

 

[Freeze215]

11.5 city / 15-16 hwy before 6" lift

10 city / 13 hwy after lift (increased weight and wind resistance killed mpg)
