Can anyone point me to the torque specs for stock wheels? I have the chrome wheels that came on the truck...
Thanks!

 

Yours is the 12mm lugs. Ford says use 100 ft lbs for those. It may also be stamped into the lug nuts.

 

The factory spec is 100 lbs. on the pre 04.

 

ill third this one and agree its 100ftlbs

 

Unless it's the 21mm lugs with 14mm thread diameter which requires 150 ft-lbs.

If you use a 19mm socket to remove the lugs, it's 100ft-lbs.
If you use a 21mm socket to remove the lugs, it's 150ft-lbs.

 

ok so does this mean that when I use my stock wheels I use a 19mm so that 100ft-lbs and when I use my summer rims I use a 21mm so they should be 150??

 

Yep, - just read your lug nuts.

 

I was taught to use the valued torque according to the studs. So if your truck came with 19mm 100ft-lbs, you'll use that value regardless of what lug nut you put on there. If the truck came with a 21mm and you move down to a 19mm, you'll still use the value set for the 21mm lug nut which is 150ft-lbs.

It's not what head size the lug nut is that determines the torque value, it's the stud, the pitch, and such.

Stick with 100 ft-lbs and you won't risk stripping or breaking a stud, as long as you have correct lug nuts for the rims (ball, acorn, shank, open, etc).

(My truck is stock, 21mm, but i went with 19mm aftermarket for my off road rims, I still torque the 19mm to 150.)

 

Holy crap, our lug nuts require more torque than my neighbors ricer puts out at 6700 RPM!

 

Yes , it's 100 ' lbs, that's what it says on the nuts,- for convenience and/or if in question. You can't throw any old nuts on their. Some rims require different nuts. Ford didn't cheap out on the nuts and care for yours and others safety.

Regardless of what you were taught, the nuts are just as important and specs should be followed.

 

When it comes to your nuts, you can never be too careful.

 

That's all I'm trying to say

 

ok thanks, I'll stick with 100 since I've got the 12mm studs.

 

Re-Read I didn't mention anything about throwing on any old lug nuts on there. I said that if you have the right ones, depending on what rims you have, the stock torque specs should be adhered to. Also the 14x2.0 Lug is pretty much proprietary to Fords and a few aftermarket. Manufacturers take that into consideration prior to mass producing the lug nuts (except china). Although the 12x1.5 is more common, it is uncommon to find one that will not hold up to a torque value of atleast 100.

You will be hard pressed to find a manufacturer that will produce lug nuts rated at 80ft/lbs for studs sizes rated at 150. It's just not going to happen. Years ago, it wouldn't be unthinkable, but with the vast aftermarket rim selection today (of which stock lug nuts would not fit anyways), lug nuts are carefully thought out, well....as carefully as they could be, they generally meet or surpass the highest torque value of a stud of that size.

 

So what am I suppose to do with that?

No worries, it's gonna be alright man.
