hey, to help everybody out, look inside the drivers door nearwhere the latch is ,but on the door, there will be a white sticker in there with all the info for the truck
look for the box that says either gear or axel, and post up the 2 didget # and we'll go from there, that will tell us the gear ratio so we can be sure the truck can actually turn 35 inch tires,
but to be honest, i have just about the same sxact setup you have, but diffrent cab and motor(mine has less power) and my truck can turn my 31s no problem, but i wouldnt trust it with anything bigger in the mud, plus the setup you have now, given you have a good set of tires and the right person at the wheel , you can wheel just as good as if you have 35s
your best bet is to leave it the way it is for now, and save up for good quality parts and when you have everything you'll need , than upgrade
trust me, dont get too deep into trying to upgrade it too quick, it takes allot of work to finish
i have 4 years into my truck so far and im only 17
