Hi everyone. I wasn't sure what category to put this thread in so it's here cause it is mainly about the tires. I just bought a 85 k10 with a 4 inch lift and 35s the previous owner didn't know he needed to regear the rear end so he was running the stock 3.08s with the 35s. I am wanting to go back to stock height maybe a 2 inch lift with 31x10.50 or something very close. I wanted to some pictures of you guys set up with close to stock height and tire size.

Eh, if you can install (or remove in this case) a lift then you shouldn't have any trouble replacing both axles with a set that have the gears you want. What trans do you have?

Do they make a k10 axle with a 4.11 ratio? I think ive heard the k20 has some that are 4.11.

Ya with the 700r4 you definitely don't wanna over do it with your tire size. I think with 3.08s youd be looking at 28.5 inch tires to keep that tranny happy.

I personally would keep the lift. As well a 4" lift is just perfect for a daily driver with not to much serious off roading. with 4" your steering works out right, you don't have to extend any drive shaft lengths, keeps the drive line angles nice for longevity, keeps truck close enough to the ground to avoid towing issues, heck you don't even need extended brake lines. And it drives quite nicely down the highway compared to taller lifts. You can keep your stock swaybar with out any modification

Plus its really nice not having to jack up your truck just to do an oil change.

I have a 6" lift and I don't do to much crazy off rod stuff anymore and ive been seriously considering dropping down to a 4" just to fix the steering and drive line angles. and make it more of a factory style truck

I personally would keep the lift, put some tiny tires on there for now, and look for some 3.73-4.10 gears in some 3/4 ton axles, 1 ton if you wanna go crazy on the trails.

Way easier swapping out some axles then changing and settin up gears.

Im running 3.48s on 33s with a 700r4 but im looking for a set of 3/4 ton axles with 3.73s to run the 33s on

35s you definitely want at least 4.10s

ya from what I can find factory gears for 10, 12 and the 14 bolt SF 9.5" was 4.11s not 4.10s
But the 14 bolt FF 10.5" used 4.10s

all were available with 3.73
