I have gotten a 03 RAM 3500 4X4 srw 4.10 gears 6 speed o/d. It has 44,000 miles. What the biggest size tires I can install without problems. I don't want it to rub. Also I don't want to affect the 7/70 warranty on engine & powertrain.

305's is the largest without a leveling kit.

 

Drew,

What does a leveling kit do?
Does it raise the truck?
If so how much?

Thanks,

 

it raises the front a few inches. it is mainly for looks to make the front bumper about the same hight as the rear bumper. but doing this will allow you to go to 315's and some have been able to stuff 37's with just a leveling kit.

i have a 2 in leveling kit on my 04.5. it is basically a hard plastic spacer(some brands use steel, i think) that is placed at the top of the front coils. you don't need any steering mods and you don't really need longer shocks, although i did just to be safe. the kit is about $170-180 i think.
