just purchased a 72 custom/10 4x4 swb and looking to do small lift and 33x12.5 tires. any suggestions?

It kind of depends upon how you intend to use it. For simple street driving, you could get by with a simple add-a-leaf. If you run it off-road where there may be a bit more compression to the suspension, you need some more tire clearence. A 4" lift should be plenty.

well been lookin at some other members trucks and see that alot of the guys are running 2" with 33's but not sure what width they are going with im looking to do 12.5's. not gonna be doing a whole lot of offroading mostly just logging roads and what not when im hunting nothing major its too pretty to beat up. pretty much just a daily driver

A 2" lift will do fine,especially with 8" wheels vs 10". You can actually run 12.50/33s with no lift,but they can rub if you aren't careful. 12.50/33 w/4" lift will do it all.

when i had the stock rally wheels on my 35's with the 4in they fit perfectly. also with my aftermarket 3.75in backspace.. i think(?) the stock rallys are a 3.75 or 4in backspace right?

also if you look at my proflie its a pic with the new wheels. 3.75 backspace

**Stocker** · 08-27-2011, 02:28 PM

I have 33/12.50-16.5s on 9.75" wheels, and 2" Softrides up front. Seems to be the right combination for me. I wouldn't get a 4" lift unless you will run 35" or 36" tires -- or if you're gonna be pounding it pretty hard off-road.

**special-K** · 08-27-2011, 05:50 PM

The rallies will work great. They are like 72chevyk10 said,3.74 maybe 4" backspace. That's what you look for on these trucks in general. Like Stocker said,even with 10" rim (in 15") the 12.50/33s will clear with 2"lift,as long as you don't get extreme.

devildoc72 · 08-29-2011, 07:40 AM

**Stocker** · 08-29-2011, 10:44 AM

You got a great deal! How much longer until you come home?

Oh by the way, thank you very much for your service!!

I think mine is about a 4 inch with 33's and 10 inch wide wheels. Best thing... it fits in my garage - barely.

72chevyk10 · 08-31-2011, 12:37 AM
