So i just installed a 3'' PA body lift on my friend's 09 quad cab. it was very easy and simple other than my 04 which was very complicated. well now i need to ask a question, when lifted the dual exhausts at the same place while the bed is lifted 3" so there is a big gap now. so do you think i can go to the muffler shop and get the exhaust lifted as well or what? also we had to remove the front tow hooks because they were attached to the frame and couldn't go the 3" either. what do you think?

 

a decent muffler shop can fix the gap issue, im not sure but is the exhaust all welded or bolted? if bolted adjustments can be made there of not the shop can do the adjusting

 

thanx man i thought so too, but just wanted to make sure

 

Let us know how it affects his MPG. Talked to a guy at the dealer earlier this week who had a body lift (3"?) and he said he lost 2 mpg.

 

MPS hurts. but, you pay the price for lifting. (these trucks loook insane lifted)

 

but y would he lose 2 mpg?

 

I know this is off-topic, but did you take any pics

Also, it has to do with wind resistance. With a body lift only the body is going up so all of the components that were down low are still down low. That means their is more surface area exposed to wind. More wind touch the truck = more wind resistance. More wind resistance couple with higher rotational mass (bigger tires) = significantly lower gas mileage. It's one of those compromises that makes the lowered vs lifted debate heat up. But I've found gas mileage sucks both ways and if you just forget about what you were getting before it helps

 

There's three main things that affect mpg. The first is the one everyone thinks of: the thirst of the engine. The second is the weight of the truck. This mostly affects mpg during acceleration or city driving. And the third, as mentioned, is aerodynamics. Dodge spent a lot of time getting the coefficient of drag for this truck pretty low to help achieve the mpg it gets. As soon as you mess with that (any kind of lift), you will see a drop in mpg - mostly at hwy speeds. The faster you go, the greater the resistance. It almost becomes exponential at highway speeds.
