hi im bryce and im 17, i drive a Custom deluxe 20 with a fresh rebuilt 350 bored .030 over thats pushing about 350-375hp with a rebuilt TH350 3 speed automatic and a NP 203 transfer case thats 4 WD all the time. i also have a GM14 bolt FF rear w/ 4.10 gears and a Dana44 w/ 4.09 gears up front. i dont know what size tire yet cause im not sure what it can handle without getting new gears. any suggestions would be greatly appreciated. thanks

It actually doesn't have a lift on it but it's already pretty tall for stock but when I get money I plan on maybe getting a 4inch at most...cause yes it is my daily driver, but I would like to take it out every now and then for some fun

I would do 35's or 36's with a 4 inch lift. I had a 79 Chevy 4x4 halfton a while back with 36 inch tires and 3.07 gears , but took out the 350 and put in a 454. That combo worked great for me, more torque not lower gears.

go big or go home..lol...IMO.....but seriously, with 4.10s you can run 38" like nothhing...as for a daily drive, 33-12.50-15, nice looking tire...

remember a truck looks better with the fender wells fulll then a truck 20 feet off the ground and diffs draging...IMO
