Wheel Studs Too Short?!

[tajvelocity]

Is this not enough thread through the lugs? They're finger tight.

Stock steel spare for comparison:

I pretty much have to use the alloy deer hooves in the first pic. I'm ditching the 2.5" lift on my truck and the 31" tires and my Cragers won't work with the 2" drop coils I just installed. If that first pic looks unsafe to you (again, just finger tight in the pic) what are my options? Extended thread lugs? Longer wheel studs?

I hate to put this in the urgent thread but I have to get this figured out and my truck out of my quasi brother-in-law's garage before they get back from vacation on Saturday. I still have a ton or work to do and I keep running into problems! I just got these wheels from the junkyard with some so-so tires and I want to use them to get my truck closer to the Earth. They looked like they would fit fine but now this.

HALP

you can easily get longer studs but it looks like plenty from what i can see.
looks like in the pic the stud is all the way through the treads of the nut if so you got no problem at all

 

[tajvelocity]

There are still like 2 threads showing in the first pic but there's still about 5 rotations of the lug worth of stud thread in there.

 

[kunar]

how many threads actually engage? how many turns?

 

[adsm08]

I would run it down tight and then look at it. If all the threads of the nut are engaged you won't get any better grab so it doesn't matter.

 

[tajvelocity]

I just checked again and I get about 9.5 or 10 lug rotations. I tightened it down pretty tight with a wrench and it still looks about the same as the photo above. Dang!

I guess when I'm finished with the front end work I could just tighten them to spec (like 100 ft lbs I think) and hopefully that will be safe enough to get me out of dude's garage and back home. In the meantime I could order some extended thread lugs (Gorilla brand or something) and see if those get me some more threads to bite on. 2 local auto parts stores had nothing like that.

Whaddya think?

 

[kunar]

ten is probably about bare minimum IMO, would like to see more like 15. probably would get you home just fine, but wouldnt be ideal. just my humble opinion.

 

[tajvelocity]

I wonder if I could even get 15 with extended lugs, assuming I can find them for my truck. I didn't know they existed until today. Any experience with those?

I'm about to start reassembly. No turning back now.

 

[adsm08]

Get them to 100 ft lbs, go home, re-torque to 120. If they don't blow out, run with it.

But then, I like to run 'er till she blows.

 

[kunar]

10 threads is about 1/2", 15 would be about 3/4". ideally length of thread engagement would be 1.5x diameter or more, but 1x will probably get you by.

on a side note, those wheels arent getting caught up on the hub, are they?

 

[tajvelocity]

That's a good thought Kunar but I can feel the back of the wheel meetin the hub mounting surface with my finger and the meet right up. This is a weird predicament right?

 

[adsm08]

It's not that wierd. Those wheels are just thicker. I think those are the correct lug nuts though.

 

[tajvelocity]

I wonder if trucks that come with aluminum rims have longer studs, and whether or not I could just get rotors designed for those trucks. Too late now, I have the hub and bearings in and bolted up. Then I realized that the upper bolt holding the caliper mounting bracket to the spindle is different with the Fabtech spindles I have and will not work with my stock spindles and I gotta find two replacement bolts.

Might try these lugs:

those look like a good solution as long as that extra length will fit through the hole in the wheel...
