no, without a speedo healer it will be the same as a stock speedo gear.So you do have to buy something additional to make the JB SS work?
edit: wow i'm late to the party. now I'm caught up.

I've done a fair bit more checking on this and near as I can tell the tolerance for the interference fit with very high quality stuff is 6 thou to 15 thou and 15 being on the very high side.Update on the hub kit install:
Yukon sent the wrong wheel studs. They are way too fat for the holes in the flange. The knurl diameter is .608 and the hole diameter they are being pressed into is .583. That’s a .025 difference and the tolerance is supposed to be .005-.01. Blaine said he’s had to change the studs or ream the holes bigger the last 5 installs he’s done. On top of that the studs don’t even have the shoulder they are supposed to have for the rotor to press into. I don’t get how Yukon fucks this up so bad. Will call Randy’s on Monday or just get new studs myself so I can get this done already.
Moral of the story is if you install a hub kit CHECK YOUR STUD DIAMETER
And to clarify that is tolerance when measuring the diameter on the actual knurls or just below them? ARPs website showed their measurement on the knurls but I remember you mentioning a measurement below themI've done a fair bit more checking on this and near as I can tell the tolerance for the interference fit with very high quality stuff is 6 thou to 15 thou and 15 being on the very high side.
Basically you want a light interference in the smooth section where the knurling isn't. Just enough to stabilize the stud so the knurls can do their job of not letting the stud spin. If the hole is larger than the smooth bits, you are relying on the knurl to center the stud and stabilize it in the hole.And to clarify that is tolerance when measuring the diameter on the actual knurls or just below them?

Right so if my under the knurl measurement is only .013 bigger than the flange hole is that technically within tolerance even if the knurled section is .025 bigger?Basically you want a light interference in the smooth section where the knurling isn't.

Ok so the tolerance range is referring to the actual diameter on the knurls?
Yes. The studs we are dealing with are not quite the same as a normal one with knurl right under the head. That style usually has a finer knurl. The un-knurled section on this style should be a light interference fit to stabilize the stud. The same is true for the shoulder that registers in the rotor hole. It should have a 0-3 thou fit.Ok so the tolerance range is referring to the actual diameter on the knurls?
Makes sense now. Sorry if I’m a little slow this is my first time dealing with wheel studs or hubs at all for that matter. Pretty cool to learn about all the fine details that go into just one component of a Jeep.Yes. The studs we are dealing with are not quite the same as a normal one with knurl right under the head.

To be fair half of this trouble was self inflicted but the other half has still been yukonThey aren't making it easy for you!
Yeah. He sells pads for factory calipers. They are different from the bbkYou have the those pads on factory calipers?
