MPG and ride

Looking to add 35's and 2.5 lift to 2016 Rubicon unlimited geared 4.1. I understand I will loose 3 to 4 MPG and perhaps some of "smoothness". Specifically what do I need to add to get some or all of that back? And what are the approx costs if a shop does the work?

Remove the 2.5" lift and put the stock wheels/tires back on.

Probably about the same as what you would pay the shop to install the lift and wheels/tires to begin with.

If keeping it stock-like, comfort wise, is a high priority to you I would recommend a budget boost. Also do your research in tires and they effect the ride quality a lot. I think you'll have better luck with and all terrain vs mud terrain. Look for one rated high in comfort. Good luck.

Oh yeah, no one will be able to give you an estimate on how much a shop will charge you, except that shop. Give them a call.

IMO
Skip the lift, add Metal cloak fenders. Throw on some 35" Duratracs and call it good.

Maybe a level kit to top it off.

there is no way to "get back" the lost MPG from going to larger tires/lift. If you want to have the least impact on MPG, don't go with larger tires, or better yet, throw on some base 16" steelies with smooth tires

of course there is a way to get back the lost MPG....
when you lift it and put big tires on a jeep you are:
  1. adding a lot of unsprung weight(the larger tires)
  2. taking the non-aerodynamic jeep body and putting it even more up in the air...

so to undo the MPG hit you just need to fix those two issues:
  1. replace the non-aerodynamic jeep body with one of those little kit car fiberglass sports car type bodies to get the aerodynamics back... and maybe loose some weight...
  2. loose even more weight by removing anything that isn't absolutely necessary/nailed down...
  3. maybe consider a diet to personally loose some weight (may not be applicable to you)
weight is one of the big things here... I forgot the actual conversion but I thought it was something like 1lbs unsprung (ie wheels/brakes/etc things not held up by springs) = 10 pounds sprung (ie body/everything else)
or was it 100 lbs = 0.25 seconds in the 1/4? hard to keep track of these rules of thumb...
anyway weight = Bad MPG.... you need to remove a lot of it just to make up for the tires alone...

or just convert the engine to:
  • diesel
  • hybrid
  • steam
  • electric
  • fusion
  • fission

I'm averaging 320+ per tank and high 17's, low 19's mpg on 35's.
