End-all answer to S10 axle widths?

I've searched many forums over the past couple hours and have found nothing definitive. I'm trying to find accurate measurements of S10 axles, not "I think it's about xx inches wide". I need to know 2WD, 4WD and ZR2 widths from WMS to WMS. A guy has an 8.5 (or 8.625) with G80 from his ZR2 for sale for $150. I figured it's a decent deal if I could use it on my 2WD. I planned on using a 4WD rear for more track width, and using spacer adapters in the front to widen it the same amount over stock. I need to know the definite widths of these axles so I can determine if the ZR2 axle would be excessive, and if I should stick to the regular 4x4 axle.

Re: End-all answer to S10 axle widths?

I forgot stock EXACT measurement but I know where to find it,

But basically.

4wd, 2" wider per side than 2wd
ZR2 4wd, 4" wider per side than 2wd.

Re: End-all answer to S10 axle widths?

The wheels I'm using are 17x8 with 0 offset (4" BS). I'm thinking that I'll like the width of these wheels on a ZR2 axle, but the front will require an LT kit and a spacer. I need to see a pic of low-offset wheels on a ZR2, and I figure there's more of a chance of finding a ZR2 with ZQ8 wheels for reference. So, would anyone know where I could find a pic of ZQ8 or Xtreme wheels on a ZR2? Or maybe a forum with someone on there that has such a setup and I could hound them for pics? What would be the widest spacer one would consider "safe"?

NP, send the 750mL whiskey to me lol.

You can buy LT from any fabbers on dezertdimes.com, getting it 3.5"-6.5" are doable with coil-coilovers and with that rim and backspacing, you may not need spacer.

Once you get LT taken care of then you'll be able check if you'll need spacer or not.

I want to keep everything in factory proportions, just wider. So, if I use that ZR2 axle, my rear wheels will stick out 4.25" further than where they're at now. I'll need 3.25" longer arms if I use AIM spindles and 2.25" if I use Fabtech spindles. I don't think I'd mind a 2.25" spacer, so I could save the money I'd spend on an LT kit and put it towards the more expensive Fabtech spindles. I just don't think I'd wanna use a 3.25" spacer, that just kinda scares me.

Yeah that's all the long travel suspensions do, longer control arms equal longer range of travel. Your lookin at big bucks though just for a wider stance.

Cheap and easy is a set of wheel adapter/spacers. Not the best solution if your hard on it, but it's the cheapest and easiest way to widen the stance.

Well, I ended up with a set of Fabtech spindles because I got a package deal on them. And, I have the ZR2 axle. AND, the wheels I'm using are 8" wide with 0 offset (4" backspace). So, my rear wheels will be moved outward a grand total of 4.58" per side from where they're at now (I have stock Xtreme wheels on it now). So, accounting for the 1.5" the spindle will give me and the .33" the wheels will give me, I'll need 2.75" more width in the front to keep my factory proportions. If the AIM LT kit is 2.5" per side, then I think that'll be close enough. If I find that I'm missing that .25", I'll get longer studs and a .25" spacer.

What do you mean by "hard on it"? Would you say that I should be fine with ~2" spacers on stock CAs if my truck is on paved highway 98% of it's life? BTW, my tires are 255-75-R17, so a tick under 32".

Re: End-all answer to S10 axle widths?

I'm thinkin hard on it as in offroading hard. The spacers would put added stress on the wheel bearings because of the tire being further out and adding leverage. As for road driving it, I'd see no problems, at least no problems for quite some time(still could wear on the bearing in time).

The lowered guys use spacers all the time to fit vette or front wheel drive wheels, and I havent read much dislikes from them. I'd just get some new wheel bearings just for the heck of it, they are cheap enough. I know 992drjimmy ran 2" spacers in the front with no issues while he had his lifted truck, a couple other guys have also. I'm going to get some spacers when I get my tax returns back, most likely just 1.5" just to even the rear up more with the front. I'm gonna put them in the front and see how it looks for sure.

Well, I feel better about the spacers. Maybe I'll try 'em out for a while until I can save the cash for the LT kit. I just got new bearings and races when I did my front brakes about two months ago, so I should be okay. I'm also gonna get a full set of Power Performance BJs. I guess I should order them now so I'll have a better chance of getting them by summer!

BTW, Fabtech's instructions for the spindles says:

WHEEL SPACERS MUST NOT BE INSTALLED WITH THESE 3" LIFT SPINDLES!

Is that to prevent excessive wear to the bearings and/or BJs, or is it because the spindles could break (spindle separate from the knuckle, etc)?

The year of truck really had nothing to do with the width of the rear end, except for the years that ZR2s were made. And, yes, a 4x4 rear end will be a direct swap for your truck. What? listed the different widths in the third post of this thread.

Covering their backsides. They also say don't use wheels with different offsets. Basicly you can't sue if you break your truck or kill yourself using the part "improperly". If guys can jump trucks with these spindles, I don't see how putting a spacer on it and driving around town is going to hurt anything. Heck I have watch stock trucks launch 4-5 feet off the ground at the sand dunes over and over with no parts breakage. The spindles are way heavier built then stock for sure.

Check these..

I figured as much, but wanted to hear someone's experienced input.


I was wondering if anyone made hub-centric spacers. Thanks for the link. I can slip a $70 purchase by the wife much easier than an $800 one!

Re: End-all answer to S10 axle widths?

Curiosity kept gnawing at me, so I called AIM. The sales rep told me that their LT kit was 3" per side. Everything I've been reading said it was 2.5" per side. So, are the arms actually 3" longer than the stock arms, but accounting for the arch they swing in and with the truck on the ground, you would net +2.5" per side? I'm not really that concerned about a half inch, I'm just curious about some details of what I've been reading.

BTW, if anyone's interested to know, AIM's LT kit on their website comes with a 3" coil and it's $895. It's $825 if you want the kit, but not their coils.

I hate to bring up an old thread but I want to nail this down because I have read that the 1990 and earlier differ from the 1991 and later S10 rear axles in width (as well as 4X4 and 2X2) giving 4 different widths...

If xtremist's post (and post 3) is correct, then there are NOT 4 widths, but just the three mentioned. .... Right?

(FWIW I am using a 1992 2X2 axle in my rod and it is indeed 54.5 WMS - WMS)

Cool Re: End-all answer to S10 axle widths?

Anyone have a "left over" narrow 54.5" WMF to WMF axle assembly, complete with 3.42 gears for sale? Drum or disc, open or Posi? Do you think the axle and drum/dick could be redrilled for 5 on 100mm wheel bolt pattern? this will be going on a 1969 Opel GT if the dimensions work out.
Preferably in the pacific NW, ie TriCities area of Washington state.
