JTRD mopar 2 lift and MPG

[Jefe1018]

I picked my JTRD up from Chapman in pa day before yesterday. I'm 600 miles into the return trip to Orlando. Have not been hand checking mileage but truck is staying steady at just under 21 and I've had 37s on it w no lift from 68 miles. Mostly 80mph on the interstate with a little gunning here and there.
The touchscreen/ uconnect/ Android auto almost makes me want to set the whole thing on fire but you will NOT be disappointed in the diesel!
And the ride with 37s is a whole lot better than the factory tires.

For reference (and to show off my new truck) this is 37s and no lift.

I am curious if you calibrated your Speedo after the fact?

1.5" spacer up front, 3/4" spacer in the rear, 37's, diesel. Truck has about 4500 miles, been on this setup since 900 miles. I average 21-22 mpg.

On a beach run a few months ago, I set my cruise at 84mph and let it eat. Avg down to 19.2 with 4 people and of course the load of beach crap in the bed.

Thats a good looking truck there. Why not 1.5" spacer in the rear as well? If you pull a heavy trailer load, won't the back sit way lower ? It looks like it is sitting a good bit lower now but I don't know if thats lack of the 1.5 inch spacer or because the bed is loaded with tire weight. Either way, it looks good!

I don’t plan to tow with it, if I did, I would add bags as I like the level look more.

I think the fenders make it look lower, and it’s a good bit of weight with 4 rims/tires, plus, these springs are soft.

helps us flex when theyre soft, i think bags would be a good idea i had them on my Tahoe.

I drove by gladiator 2700 miles from AZ through the Rockies and I was averaging 25.9 mpg while doing average 75 mph. I have the mopar 2 lift with 3/4 daystar spacers and running 35 ridge grappler w/full spare. I was pleasantly surprised. Since then I have been in 23-25 but I think it's due to winter fuel

I'm not getting over 18mpg in day driving. im afraid of what's happen when I put on a lift and 37s...

Stock? I’m stock and can’t get below 25, all city hovers around 26-27, highway I’ll see 28-30 (using the cluster)

And I’m awake… JT is being picked up today with 37’s and the mopar lift. I’ll report back on my MPGs driving the 700ish miles home over the next two days.

On stock tires I was getting 23-24.5 daily, on 37's, I still get 22-23.

Something does not seem right here.

Picked up my Rubicon Diesel with the Mopar lift + 1.5 inch Teraflex spacer and Grabber 37’s in Nampa Idaho this morning. Did about an hour of errands to get on the road, maybe 20 miles of city driving at a reported 24mpg.

From Boise to Twin Falls I did the 80mph speed limit to just above - 18mpg per the computer.


I think it’s fair for pushing a brick nearly 90mph, power was not an issue just basic physics.

Ok, I drove the speed limit at 55mph and 65mph and I got around 30mpg. If I drive like I always do, I get around 18mpg...
