need some input

[murphy2024]

I just have a couple questions. any advice is appreciated
heres my setup for reference. Right now i have new torsion keys which brings my front up about 2in and i have 2in blocks in the rear. Im putting on a 3in body lift next week. I just want to rnn 33"x 12.5" tires. Im going to get new rims. cragar soft 8's in 15"
1) should i get 15x10 or 15x8 rims?
2) will 12.5's rub when i turn?
3) Will i be okay running 33's with stock gears?
i looked through the body lift thread but i didnt find anything specific that

you can run those without the body lift. they wont rub. at stock height they rub the edge of the bumper at 5" total lift you clear them real well. I have that tire size on 15x10 and i like how it looks.

i would suggest no body lift and 15x8s

1. 15x10's with a BL 15x8's with just a crank.
2. 12.5 should be ok depending on the wheel offset, might need a little trimming. I'm clearing 305/70R16's on stock nbs wheels with about 2" of crank. I've seen 35x12.50's on 15x10's clear with 2.5" of crank & 3" BL.
3. It depends on what your stock gears are, you will feel a difference but it's up to you if it's ok. I'm fine with my 3.73's, @ 70mph I'm turning 2000rpm.

you know the new keys did nothing for you right? The stock keys will get you 2 inches. keys do nothing for an obs truck.

guys clear 35's stock with just a crank, with a 3 inch body lift and crank you should be able to do 10's and 33's no problem. Every truck is different though.

I can tower over 265's without a body lift or crank on mine, but just recently cranked mine up and didn't get much since my bars are sagging being 1988 bars. it's about as far as it needs to be though it's almost on the droop stops. You don't want to go further then that.

im running 33s with a 15x10 on my 88 no problems what so ever
had no problem with the stock gears but still with with 373s with a locker

the backspacing on the wheels i want to get is 4" on the 15x10's
