Lowering my lift

[Shooter04]

I just did a round trip to Austin and back to Houston, averaged 13 mpg on the highway babying it, running a half bottle of diesel kleen in both tanks. My chip was set to Eco the whole way never changed it. I know my truck isn't going to get anything outstanding, but i was hoping for something better than 13 mpg when not even towing anything. I've been thinking about lowering my lift for a while and this just about made up my mind.

I see my lift is set up on two blocks front and rear, a 4" block with a 2" block stacked on top. Also i believe i have 3 added leaf springs on my front axle, compared to how many i have on my rear axle. Although that may be how it comes, i'm sure you guys would know more than me. My question is, if i take out the 4 2" blocks i have out from under each set of leaf springs and drop my truck 2", will everything still preform properly? Will it sit lopsided or is there more i need to do? It can't really be that simple...right?

Right now my plan is pretty simple, take off my wheels, slip out the 2" blocks, put the wheels back in place...and that's about it. Any info or tips on how to do this will be greatly appreciated.

so you have a 6 in lift lift and 32 in tires? i dont know if lowering it will make much off a difference on mpg? i have 35's and I get 15 putting my foot in it a little,

Oh i see well good luck with it.

I just took a trip to Atlantic city and my final average was 18.8 mpg I have a 10 inch lift with 38 inch tires. It probobly helps that I have a 6 speed though.

It's not really the lift that causes poor mileage. It's the tire size change and in most cases the gearing that causes a change in mileage. I still have 373 ratio gears with a 38 inch tall tire and a 6 spedd so I can cruise down the highway at 85 mph and stay rite around 2,000 rpm I was having a problem with fuel mileage and it actually turned out to be the copper washers on a couple of my injectors causing the problem. I couldn't figure it out untill I took the injectors out to put in my swamps ones and my fuel mileage jumped back up.

I don't think taking out your lift will do you any good. I average 18mpg on the interstate at 75mph with 35's and 3.73 gears.

Stripping your lift is going to do next to nothing for your mileage. As stated, tire mass and gear ratio are the largest factors in hampering or helping mileage, aside from engine condition, drive train set up, and driving habits. My truck averages 20mpg highway if I keep to the speed control. Stock height, 3.73 gears, 285/75r16 BFG ATs. Yes, Blizzard is a 4x4.

I do not believe that it is that easy. You would need a new trac bar bracket for a 4" lift so it would not push the axle over. Steering should be fine but you might have to adjust it a little to get the steering wheel stright. But i dont think that lowering the truck is going to to do anything for your fuel economy. Not sure if its the same way on the 7.3 but most people say the hotter tunes yeild better MPG.

I wouldn't say that. With some tuners it is true with the ones the know what they are doing though there economy files are the best
