Netters
A couple of questions.
What torque should front wheel spacers be tightened to when attaching them
to the original ft wheel studs, and I assume the Alcoa 140 remains the
same on to the spacer itself.
Also, is there any reason why I shouldn't use them...??
All input is appreciated !
Thanks

I'm probably not in the majority, but I like them. OK, I admit it's all about form, rather than function.
Only reason I can personally see to NOT use them is if you're considering doing a Hubler 1-ton front end any time soon, which from my understanding will obsolete the separate spacers.

Torque the spacer 120-140 as Al parts can settle in more than steel.

Thanks for the numbers guys...my coach seemed to handle ok, but would I
notice after 16 years of ownership and 100,000 plus miles...it's just like
slipping my feet into my slippers...they fit well but I really can't say if
they're comfy or not.. <VBG>

Good morning, Jim and group.
Can anybody provide the proper torque for lug-centered
cast aluminum wheels such as the KMC XD-775 Rock Stars?
Wasn't the torque for the hub-centered, flat-nut, steel
wheels something around 200 ft-lbs?

Centering type actually has nothing directly to do with the torque required.
That said the type of nuts and nut / washer combination does.
I suspect that you really have hub centered wheels that for some reason you choose to call lug centered. Lug centered wheels use a tapered nut. Every hub centered wheel I have seen used on a GMC had a nut/flat washer combination. It is those different types of nut/washer combinations that call for different torque settings. On the steel wheels with the built in one piece washer on the nut the settings were in the 250 range. On the Alcoa and Eagle hib centered aluminum wheels with separate nuts and washers that could turn independent of each other ,the torque setting is around 140 maximum.
If you truly have lug centered wheels (with tapered nuts), I can not give you the value because I have never seen a lug centered wheel with tapered nuts used on a GMC. I know the studs are 9/16 x 18 so If you want to search on the internet for a vehicle that uses that thread with a tapered nut (lug centered) wheel, you at least have a place to start. I do know something uses that size tapered nut because my local auto parts store stocks 9/16x 18 tapered (lug centered) nuts.

To expand on what Ken said, I DO have lug centered wheels on the front of my GMC. They are Dodge pickup wheels and are held on with tapered lug nuts. When I installed them, I asked my mechanic friend to look up the torque spec on the Dodge 2500/3500 series truck with alloy wheels. The spec was 135 ft lbs. I torque them to 140.
Disclaimer: This is Just What I Do. Your mileage may vary. What I do may be viewed as "stupid", "dangerous" or "uninformed" by the "experts".
However, I have been running these wheels for almost two years now, and have never had a problem with them loosening up. I used to check the torque on them periodically and, after the first time (when they moved about 1/16th of a turn) I have never had to tighten them up.

If your comment below was meant for me, Ken, I
KNOW the difference between lug and hub centered
wheels. Mine are lug centered, just as almost all
modern (AFAIK) wheels are built. The hub on the
XD-775 Rocks Stars are larger than the GMC hubs.
Since there is no indication in your message as to
what or whom you are replying, I can only guess.
Maybe that is the "forum" way where there is no
tie-in to earlier messages.

Mac,
No idea on the Rock Stars, I would suggest contacting the manufacturer directly. How's that for demonstrating an acute grasp on the
obvious! ;-)
I checked Maintenance Manual X- 7525 Page 10-2 MAINTENANCE - WHEEL STUDS - TIGHTENING WHEEL STUD NUTS and I noted that it says;
"Nuts should be tightened to 250 foot-pounds torque. . ."
I had drawn a line through that and written in "130-150."
I also checked X-7625 and X-7725 but there wasn't anything about torquing the wheel nuts.
I then went to the Service Bulletins and found NADA.
I did a Google search for Lug Nut Torque and came up with this:

Rob M.

If it does not drive right, it might get worse when you install them. Knowing you, it drives right. I never had them on the stock
setup but I like them on the Hubler.

If you ever look at the front bearing assy and how the CL of the wheel is supposed to center to the setup, then you understand how this increases load on the system by lengthening the lever arm. Looks better yes, but by geometry, increases bump steer and torque steer.

Re Lug centered wheel nut torque on a GMCMH. My GMC Yukon has metric wheel studs/nuts. They are M14 which is pretty close to 9/16". The thread pitch is 1.5.
The torque for these nuts on the GMC steel or aluminum wheels is 140 Ft/lbs (or as some say lbs/ft)

The forum lists messages in threads and sub threads so the tie it is always there. Sorry I forget emailers can not associate responses with the messages.
The purpose of my reply was to make sure that you really have lug centered wheels with tapered nuts. Some people here buy hub centered Eagles wheels and call them lug centered because they bought ones with .031" bigger centers. I just wanted do make sure you really have lug centered / tapered nut wheels.
Carl posted that his lug centered wheels with tapered nuts were also suppose to be 135 ft-lbs, so it seems that the torque is very similar on tapered nuts to hub centered aluminum ones with the moving washers. So it seems that 135 should be good for either type of wheels.
