Front End Leveling and Fuel Economy

I've been thinking pretty hard about adding some Bilstein 5100s to my 05' DC......wanna bring it up just a little. However, I'm wondering if I would see a drop in fuel economy by doing so??? What I invision is running the 5100s on the second notch (about 1.25" of lift)....wanna make sure the final product doesn't look like the truck has something heavy in the bed. Seems like it wouldn't be an issue, but not sure how the aerodynamics might be changed.

Re: Front End Leveling and Fuel Economy

Good question. Theoretically raising the front increases the profile of the truck and would have a negative impact on fuel economy. That being said, how much of an effect, is up for grabs. If I had to guess I would venture a half a MPG on the highway - less of a an impact with in town driving. I would be really interested in your results and hope you will post up your findings.

Re: Front End Leveling and Fuel Economy

My friend installed a Toytec 3" leveling kit on the front only on his '09 double-cab...different engine than you, but his mileage decreased by about 2 mpg local, and 1 mpg on the highway. Hope that sheds an idea.

Re: Front End Leveling and Fuel Economy

I would listen to Highway. His words are gold when it comes to research and experience. Just my 2cents.

Re: Front End Leveling and Fuel Economy

I raised the front about 1.5" on my 06 4x4 DC and made the change to a 265/75/16 AT tire from a 265/70/16 HT and over 7 months I haven't noticed much of a change. I recently did a 600 mile trip and got 17.5 mpg - pretty much equal to the best I got before the switch.

Overall I wish I could find a way to squeeze some better MPGs out, but considering the negligible change I've noted, the leveled (or near leveled) look/stance and more capable AT tires are def worth it.

Re: Front End Leveling and Fuel Economy

I also did the Bilstein 5100s at the 2nd notch in the front. I was concerned about the bed level as well. In fact I asked the shop to level it, they placed it at the 3rd notch and it was notably not level. They offered to take it to the 2nd, which required an alignment, and it is perfect.

Also I did feel like the gas mileage is a little worse, but I don't keep a solid number and I always fight an urge to get on the pedal. In the end I'm happy, I feel a little more confident driving through some trails and I like the stance of the truck.

Re: Front End Leveling and Fuel Economy

if you level and keep the same tires, you wont see much as a difference in MPGs. now adding bigger A/Ts ot M/Ts then yea MPGs go out the window.

+1 here. You'll take a larger hit from the heavier tires than you will a level kit. I've been there and done that.

Now, the key is go buy lighter wheels with good tires and come out net or negative and you lessen the impact, but wider tires can offset that a hair due to wind resistance.

I would observe that wider tires hit fuel economy because they have higher rolling resistance as well as more rotational mass - the aerodynamic resistance would be negligible.

Good input from the members here - always nice to see some dialogue taking place.

my truck is leveled 2' with the Bilsteins and is currently rolling on 265/75/16 cooper AT3 tires. This was last weekend on a 300+ mile trip from charleston sc to Atlanta GA. All interstate and speeds between 75-80 most of the time. I just changed from 285/75/16 tires and would definitely agree that the tires you have will make a lot bigger difference in MPG than any type of lift will.

That 19+mpg is nice! How do you like the BAMuffler (I've got one ordered myself)? Feel like it helps with that fuel economy?
