    I am in the process of installing 1/4 inch spacers on the front of my truck so I can gain some tie rod clearance. I have good clearance now but it seems that the lug stud doesn't have enough thred. I can get about 3.5 to 4 turns with the lug nut when they are hand tight.... Think its enough to be safe or should I figure something else out? I am running 16.5 inch rims so I have been having problems with backspacing from the get go. Thanks!

    I wouldn't trust it . I would want at least most of the lug nut taken up with lug threads , like the factory closed end nuts .

    If you were drag racing , they would want the lug nut diameter sticking out open end lug nuts . That says what you need to know about safety and the threads .

    OK thats what I was figuring. Thanks for the re-inforcement. How much meat is on those tie rods so I can clearance it away from the rim? THanks again!

    It turned out I didn't need that much more clearance. I took my grinder to my tie rod and now everything is good to go. Thanks for the help though!

    FWIW one bolt or stud diameter worth of thread engagment is usually considered the minimum.
    Not sure why NHRA has that stick-thru requirement, but that usually results in more thread engagement than is absolutely necessary. Not a bad thing in this case, but might not always be possible.

    haha no thank you! I had dreams of loosing my rim and tire going down the road... then I realized it was a nightmare and I decided I'd rather have too much thred than not enough.
