Hummer beadlocks on WT axles under an NT wag

[Hump]

Whew that's a mouthful! Here's my thinking. I'm picking up a '66 wag in a week, and I want to run 1 ton axles under it. I want to run at least 38's, and my theory is that the deeper backspacing will help keep the tires closer to the body. Can I do that?

[River Beast]

yes.... but watch your spring to tire clearance....

[Booger]

Use a tape measure and measure the distance from where the rim bolts to the axle to the leaf springs. I tried to put 33/12.50 on a wag using aftermarket rims from the junk yard, but they didn't fit because the backspacing was to much. However the stanard rims did work with 33/12.50

good luck

Using the 1ton axles... shouldn't have a problem since that are 6-8" wider... you just have to make sure your steering linkage clears the rims as well... running full high steer over the springs will cure this problem...

how wide of a tire do you plan on running?

If my calculations are correct (I doubt they are)... A full width axle (69" wms to wms in front and 67" in back) with 12.5" wide tires on hummer rims will net a total width of 72.5" in front and 70.5" in the rear. In the front that would be about 6" between the inside of your tire and the edge of your leaf spring. Is that enough? Heck if I know... i've never measured it. If not, you have steering bumpstops.

Assuming the leaf spring/tire contact isn't an issue... I believe you have issues with your steering linkage contacting the wheels... the grinder can maybe take care of that.. but it will weaken the steering arm.. there are other options... $$$ permitting..

I will be running Hummer wheels on my Wag. I have a 14 bolt out of a Chevy van, WMS to WMS on it is 70 1/2" I have a D60 out of a Dually Chevy K3500 I am not sure of the WMS to WMS on that, but without the Dually extensions on the hubs I can not see running Hummer Wheels on any Single Wheel Front axle. Custom Hummer wheels can be found here Hummer Wheels (http://usa6x6.com/military/rims/)

You will have to put some type of wheel adapters/extensions on the front and back axles for the tires to clear your springs and steering linkage. 4" is pretty much what people agree on is good for the minimum extension with Hummer rims on single wheel axles.

I have the same axles Crazy has, Hummer/Beadlock rims, and 38.5 x 14.5 SX's on mine on it clears perfectly as shown in this pic:

Am I wrong in thinking that the springs are closer together under an old nt wag than say a 1 ton chebby? I figured the narrower spring spacing would allow the deeper offset and keep the tires closer to the body.

Pete, sent you a PM.

true Hump... but the steering linkage still may interfere with the rims with too much BS on the rims.

The 1ton front GM axles are the same 32" centers as the FSJ's...either N/T or W/T

the rear perches need to be relocated on the GM axles a bit more outboard...on mine anyway

And my 1972 waggy that originally had a Dana 30 is now sporting a 3/4 ton GM 10 bolt with original springs and original perches. http://mp3car.com/usersites/tom/tuck/
That's in the front. I'm not sure about the rears cause I just hacked my original mounts and fabbed new ones lower on the frame to elminate blocks.

The Dually 1 ton axle out of a Cab and Chasis truck is usless, it is way to Narrow. I think it was 44" Backing plate to backing plate. The axle to use is from a 1 ton Dualy Pickup or a Van I measured the one I got from a Van and it is 70 1/2" WMS to WMS.

Well I finally measured the front D60 WMS to WMS, :eek: :eek: 77" is what I have compared to the 70 1/2" rear. I went to the Junk yard and found 3 more D60 as well as a 2 wheel drive 1 ton, All had 77" WMS to WMS on the front end. Is there a shorter extension? I asked a few guys this and they said not that they knew off. 7" differance is to much for me. Options I guess are run two offsets, or see if I can have the front extensions shortened.
