Torque Needed For Wheel on Kodiak Disc Brake Kit K2HR526D

Question:

In preparation to installing new rotors and calipers I noticed the stud length on new rotors are shorter then my original rotors. I carefully measured the thread length from the surface of the hub to the end or studs. So this measurement does not include the thickness of the hub or thickness of the head of the stud. On my original Titan rotors the measurement is 22/16 and new Hub in rotor is 18/16 The new hub studs are shorter by 3/8 then original hubs. Near as I can tell that is about 6 to 7 less thread engagement into lug nuts. I mounted the new rotor and hub on my aluminum wheel and I can turn the lug nuts 10 turns to snug up wheel to hub which was about 35 ft. lbs. of torque. I have capped lug nuts. So with 6 to 7 less thread engagement in lug nuts is this going to be enough to not worry about losing a wheel?

The 35 ft. lbs of torque you have now would not be enough for your wheel, it is quite a bit less than recommended. The hub on the Kodiak Disc Brake Kit # K2HR526D has 1/2" wheel bots and for that size bolt on a 15 inch wheel the recommended torque is 90 - 100 ft. lbs for an aluminum wheel (and 90 - 120 ft. lbs for a steel wheel). That said, wheel stud threads need to be visible outside the wheel nut and though there can be varying amounts of thread sticking out, as a general rule there should be three threads visible past the end of the lug nut.

I'm not sure what wheel you have, but my guess is that it is too wide where it mounts to allow you to properly engage the lug nuts. If you let me know what wheel you have, or maybe send some photos I would be able to make a suggestion on what you might need. I have also added a link to our selection of wheel options for you to take a look at.
