mpg report from 4 or 6" lift kits?

[flying7]

anyone have mpg numbers for 4 or 6" lift kits? I'm thinking the lift may just be to much.

It's not the lift as much as it's the accompanying 35" tall tires. I've been reading where it's knocking 4-6mpgs off the hwy mileage.

Yep! Some huge losses reported on our facebook page as well.. I like lifted trucks, but my main reason for purchasing was the better MPG. Not going to kill it with a lift kit/tires.

Ram spent a lot of time and effort getting the gearing set for these trucks for someone to go tinker with it...

People will always modify trucks... but my readings so far yes MPG is going to take a hit. But the truck doesn't really sit like a 4x4 which bothers me. maybe a leveling kit will make me happy.

I started with a 3 inch spacers and a bed leveling 35s and 20s Mpgs went down from 25 to 23 combined Then I went to 6 inch lift total. It went down again to 22 mpg, added a winch as well, truck is 4x4. Hope it helps

I installed a 2 1/2 inch level kit and my MPGs wasn't affected. Looks much better than the stock look and I still have the stock ride

What kit did you use? Thanks.

I order it from hellbentsteel.com. Don't get the 3 inch because it got bad reviews. The 2 1/2 works good

Thanks.

I know what you mean. Mine sits more like a 2 x 4. I put 315 75 x 17 on mine without a lift, and my millage did not suffer, it still sucks at 22 - 23 highway.
What kills milage on a lifted truck is the additional wind that gets under the truck and plays havoc with all these exposed components and protruding frame parts,and yes, bigger tires. If there was a way of streamlining the underside to prevent all those odd shaped items from catching wind it would help. Maybe a plastic shroud or super large skid plate that would cover most of the exposed items. But then, this would cause overheating of 4X4 components when you offroad since the heat from those components could not escape as easily. (Tranny heat, transfer case heat, catalytic converter heat). Its sounds like a good project for some of you younger and more energetic guys.

I also plan lifting my truck by 6 in I guess. So apart of the lift kit you say it's better to grab a skid plate to avoid mpg losses? I haven't thought of it yet, though sounds legit from the aerodynamic point of view. I was planning to keep my wheels and tires for now, just do the suspension job first. I was wondering, if that's true that I'll have to cut my control arm pockets? I've read some instructions and some like this one say that cutting is required, some say that it is not. I am concerned about this since I've got no tool to cut metal so far.
