Hummer wheels and spacers

[JeffHK5]

I have been trying to keep track width as close to stock as I can while running
Hummer wheels with stock backspace. I'v got a DRW front 60, and with the hubs puts my tires in the ballpark. Now, for the back I use a SRW 14 bolt, which
is about 11" narrower the 60. I have seen locals that run alumunum spacers that
are 8" dia. and 4" thick to get a wide stance. My question is does anybody know where I could get a set that can stand upto offroad abuse on a 4,500 lb full body K5?
Thanks Jeff

I run the stock Hummer rims on a DRW60/DRW70 and the track is pretty good. White-Rhyno runs them on a DRW60/SRW14bolt w/ spacers in the back. I am not sure where he got them, but they have taken lots of abuse w/o any problems

You would be best off to run a D70 DRW to get your track width the same.

I don't like spacers but some people have luck with them. It would be best to run a steel spacer IMHO over aluminum. Be sure to tighen up the bolts periodically if you do run them.

There is a company called ArrowCraft that makes dually conversion parts, they offer large steel spacers. You can get the spacers separate from a kit from them but they are pricey - about $400~500.

I have a set of their "Magnum" series spacers that I'll be using for my K5 (Hummers w/ dually D60 & D70HD). The spacers I have measure about 3.25" if I remember correctly.

Hummer Spacers

What I am getting out of this is that a DRW Dana 70 is wider than a DRW 14 bolt. Where does a DRW 70 make its home? In the back of a DRW Ford or Dodge
or was it pre-14 bolt in GM trucks?
Thanks for the help Jeff

Wow! What I ment to say was a DRW Dana 70 is wider than a SRW 14 bolt.
How can that be? Thanks Jeff

The DRW D70HD out of a 73-87(91) GM dually pickup is considerably wider than a SRW 14 bolt. If I remember correctly it's got a approx 73" WMS.

My D70HD came out of a 79 K30 Crew Cab Dually. I don't know what the WMS to WMS measurements are, but w/ it all bolted together my rearend is about 2" narrower than the front, which is pretty close to stock.

From what I understand, you can take a DRW D70, convert it to disc brakes, and use SRW14bolt hubs on it, and it will be the exact same width as a DRW60... so you will add about an inch per side by swapping the hubs.

I've got a set of 2 1/2" thick spacers made from 6061 T6 aluminum with 9/16 studs. If you're interested, shoot me an Email.
