Wanting to lower my truck

[Jonathan734]

Well with the way fuel is going I have decided to do some things to help my truck get better mileage. I have noticed my truck sits about 2 inchs higher than other superdutys, it has 3 leafs up front and I believe 5 in the back. I am going to 235/85/16 and I know that they will look funny the way it sits now (my 285/75/16s look perfect) so what would I need to do to lower my truck atleast back to stock? What about lowering it 2 inches lower than stock? How hard would this be and does anyone make a kit?

i would like to lower my truck also. i noticed theres a member on here by the name of lowstroke and his truck is lowered with djm lowering kit. maybe he can help us.

I don't imagine it will pay off short term, but if I was able to get 3-4mpg better and with the way diesel keeps going up it could make a big difference. I can only manage around 15 now. Anything has to help...

Get a de-tuner chip to decrease power. There was an article about a guy who took a 2000 7.3 6 speed and put a 3.08 diff a detuner and some other stuff that got 26MPG.

I could be wrong, but I don't think just lowering it would get better fuel mileage. The small tires will help, but I don't see you getting 3-4 better. I think a good econo tune on a SCT would probably get you there. Good Luck though...

I already have a TW chip with the economy tune, but haven't had a chance to really try it yet. I here many people say they can get 18-20 mpg. They are almost all running a stock setup. I think the weight difference, rolling resistance difference, and better airodynamics could increase mpg quite a bit. My truck is a 4wd though. Maybe I need to just do something custom up and post the results, there is a guy on powerstrokenation claiming 24-26mpg with a 6sp lowered 2wd truck on 235/85/16's...

2 wheel drive makes a big difference and a 6 speed helps too. have you tried keepin it under 2000rpm's? try doin under 65 and that should help you out also.

[Jonathan734]

I realize he has a big advantage over me with the 2 wheel drive and a 6sp, but he is getting 9-11 mpg more than me. I really don't think there should be that big of difference. By reducing some drag there could be some possible mileage changes, I am going to have to pay my local spring shop a visit and see what they can do for me

I bet 100% of his economy came from the 3.08's instead of the detuner, could be wrong though.

I want a two speed differential, lol. One with 3.08's for hwy speeds and one with 3.73 or 4.10's for towing/in town driving.

LoL that would be nice, one of the gearvendors units looks good but have you seen the price...
