5-6 speed conversion

[Diesel Dan]

I've heard problems with trucks running 35's with stock gearing being underboosted all the time.

I've talked to a guy who went with 4.10's and say he actually gets better mileage now.

not when you're way underboosted and smoking.

Fuel out exhaust=loss fuel with no energy actually moving the truck.

that's the way I see it.

That's what I heard, I'm no expert.

I'm running on 285's anyhow, my truck is actually used for working


.....And occasionally loading up with girls and testing the 4x4 in a muddy field. Ever noticed the unpleasant tendency of the rear tires to fill the bumper with mud?

downshifting = lower gearing samething would happen if you ran lower gears. would not downshift though.
