f-250 lift??
Hey I'd like to lift my 04 250 SD, but I don't know where to start. I want to run larger tires, 33s or 35s. I'm thinking a four inch lift would be good. I also so dont want to lose any payload capacity (softer leafs) Can I get 4 inch leafs with the same payload, or greater?? If so what company and how much $$. Also will 35 inch tires be too much for 373 gearing? can they have any othe ill effects?
any info is appreciated.

Dcycleman,
A little more info would help on your truck. If you have a PSD, you can get away with the 3.73 gears for a while. You will lose some torque, but the motor is enough to overcome the loss. As for the 5.4 or V10, I cannot answer that. A 4" would work with 35" and that is what I had for my 01 with 35" tires. I recommend going with a Donohoe racing or a Superlift. I have ridden in both and they are good lifts. I give the Donohoe the best rating. To keep the same payload, you will have to run blocks in the back. The only other ill effects I can think of is the truck looking great!! Good luck!!

If you have the V10 and you do any towing, 4.30 gears would be a good choice with 35"s. I run 4.56 gears with 37" tires and after running the numbers, i'm around a 3.80 or so effective gear ratio, which works good because I don't do a whole lot of towing.

6over,
For the V10, 4.10 effective provides about the best mileage that you will get in daily driving. 3.73 is a little too high and make the trans hunt gears on small hills. 4.10 keeps it nicely in OD and in it's optimum power range. 4.30's start bringing it back down again, but provide great power. Try to shoot for an effective gear ratio of 4.10.
My 36's w/ 4.56 puts me at 3.99 effective. 35's with 4.56's would put you right at 4.104. Right on the money.
Just keep in mind that higher gearing doesn't equal good mileage if the engine has to lug to keep up speed. This means gas is going in, but power isn't coming out.
