scuffed up my front valance!

crushNchowda · September 20, 2016

Oh yeah mine is all beat up. It's just thin plastic. After I get my wheels/tires I'll probably take that and the steps off anyway to be honest.

Someone on here did. Something like 2-3 mpgs difference with valence off and front leveled.

My truck is leveled on bilstein 5100s highest setting front & added an extra 1" w/ a 2.25" block kit in rear, took lower valance off haven't noticed any difference in mileage, to be honest my current truck that's leveled has the 6.2 & 8 speed combo & gets better mpg than my previous 2014 5.3 w/ the 6 speed.

I'm also still running the stock 39 lb Wrangler SRA's, if I were to put a heavier LT 10 ply like BFG K02's or whatever that weigh 55-60lbs+ per corner I'm sure it'd be worse.

I just noticed mine got scuffed on the passanger side. Not sure when or how it happened but i am going to use it as an excuse to either level or lift the truck now.

You won't regret it. These trucks sit so low to the ground, it's basically impossible to keep it in good shape

Anyone do a test to see how if there's a noticeable fuel mileage drop with it removed?

The valance off doesn't make a noticeable difference in MPG. The guy who said 2-3 is probably due to the level and potentially tires, but not just the valance. Ive taken mine off my 14 and 15 trucks and noticed nothing. If it was anything it would be .1-.2.

I did, it was 1.2 at a steady 70 mph over a 40 mile loop without AC...

If you run a ton on the highway, it will and it will be seen if you pay attention to your MPG (though most who say no difference probably don't do enough highway driving or recall their exact mpg to know if it really did). If you mix a ton of city in the percentage will not be noticed much (a few tenths). All depends on driving habits, location, weather, ect. The only way to really know is back to back controlled runs (as much of a control as you can do) as other variables play too much of a role.

I have my trimmed now (didn't like the look of it off as much and the off roading I do won't make or break if I can make it up or thru something) and I probably get half my mpg back for day to day driving (figure it saved me some free beers in money over the course of a year so why not). I did scuff mine too, so this helps and when these tires are gone a 1.5 front level, 1 inch rear and 265/70/18 will give more space for me...

Just need to decide if I want to do a 2.5 in leveling kit or go with a 4 or 6 in lift

I've gone both routes with my truck.

Rough country 2.5

I got wheels put on the same time as the level. Other than that, honestly couldn't really even tell the front was lifted.

Rough country 7.5

I accidentally tore mine half off when I did a little bit of off roading. It's a pretty common thing

When you did the 2.5 in rough country did you add the rear block or leave them out. I really don't want to sacrifice too much fuel economy so may just stick with the 2.5 in leveling kit.

Just the lift in the front. Even after I leveled it, I didn't really see a loss in mileage

I think that is the route i am going to go with. Just level it out with the 2.5 in the front and call it good. I have 2 small kids and if i go to high they wont be able to get in by themselves

I haven't either. Haven't noticed much of any mileage difference since leveling my front. Still have my valence and still on stock 20" Goodyears. Must be the 10 plys that made the difference for that other guy, like y'all said.

All I drive is highway. Didnt notice a difference in my 5.3 or my 6.2. In order for the test to be valid, results woyld have to be consistantly repeatable. Not saying there was no merit to your tests, but that one 40 mile loop, in traffic, means hardly anything.

Of course that's just my observations based off 20k miles without the valance and 10k with. I never noticed any changes as an overall when it was removed.

Scuffed mine on a curb when backing out, ever so slightly. Sanded off the scuff and looks good again!

Nothing that impacted a speed change so traffic was no concern. The whole point of the valance is at highway speeds which is what I ran and gave a very good idea of the impact (exact nope, but in the ball park). Considering it was ran in two directions round trip for each (east to west and back) with a maybe 2 degree temperature difference it is far from hardly anything. 40 miles is a half hour at a constant speed.

Your results could have changed a few tenths and you couldn't tell or failed to remember exactly what tenth you average (I certainly don't). You have to remember this was strictly at highway speeds. Throw in half city driving and you are down to around 0.6 difference, some regular idling time for maybe warming up the engine, winter blend gas or maybe a monthly off road trip or towing adventure and it could only have a 0.2-0.4 mpg impact which honestly unless someone logs it probably won't remember if their truck was averaging 16.3 or 16.5/16.6 a year or two ago. This is why I said most who say it made no difference probably just didn't really realize the small impact it did on lifetime average; but if you were to take a long road trip back to back you would probably notice a half mpg or more (give or take) if you keep track.

Either way it is a descent indicator at strictly highway speeds. People will always want more regardless of the results and there certainly is lots of room for someone to do more; but chances are no one wants to waste the time or money to tell people on a forum how much it really impacts because then everyone will by saying the results are false because it wasn't in a lab blah blah blah...

all my research into this has led to the conclusion that the air dam provides 1mpg better fuel under optimal environmentally controlled conditions ie. a wind tunnel.

it is standard equipment so GM can put 1mpg better rating on the window sticker. nothing more nothing less.
