Widening rear

Is there a wider axle I can throw in the rear to compensate for the disc brakes up front? It's a 6 lug 4x4 and with the disc's up front the tires stick out farther than the rear. I was thinking about a different offset in the rear but most of the wheels I'm looking at come in very few offset choices. What do you guys do to widen the rear?

Re: Widening rear

what about a 73 and up 1/2 ton 4wd rear end? you'd have to rearrange your brackets though because of the wider leafs of a 73+ I believe

Re: Widening rear

I know some people hate them..... but 1inch spacers are a heck of a lot cheaper. They use them on drift cars etc... don't know about 4X4. I have them on the back of my truck but I'm pretty tame when it comes to abusing the truck.

GM claims to have done that intentionally... and still do it.

Re: Widening rear

A spacer would be the cheapest way by far. Custom built wheels, budnik,intro,bonspeed could work too

Why would they do it intentionally? Stupid if you ask me.

Re: Widening rear

the tires ride in undisturbed dirt and do less sinking/digging in. Less likely to get mired.
This assumes you are on dry/damp soil, and not out mud bogging.

Re: Widening rear

yeah, the different track widths front and rear can also add to stability (but decrease turning radius), along with what Longhorn mentioned.


And as for the spacers, you're kind of limited because you can really only do like 1/4" or maaaaybe 1/2" slide on spacers and still remain safe with enough left-over stud thread to bite and hold consistently.
Or on the other hand, with a Bolt-on style spacer (safer), you can really only do like a 1.5 (might need more on your 4X4, I don't know the length of your studs) or larger spacer to clear the length of the factory studs without grinding them down.
If you did a 1" spacer, you'd have to cut your factory studs down to 1" length, and that might not leave much room for lug nuts, further complicating things...


And for the 4X4's do they make any newer knuckles for them that decrease the track-width, because I see CPP now makes one like that for the 2WD's with disc brakes.... ?

Re: Widening rear

a 2000+ 1/2 ton gm pickup or suv will have 6 lugs, rear disc and a wider track than older trucks. that should close up the difference. i also don't like the idea of the back end having a narrower width than the front and the 4x4's do look extra funny as you say.
