JK to TJ Wheel Adapter Question

Is this what the adapter should look like before I put the wheel on or am I supposed to buy some special lug nuts that fit all the way inside the recessed adapter holes? I didn't get any instructions with the adapters I bought and all the lug nuts that were included are just normal sized.

No - normally you use your nice acorn style lug nuts on the wheel and you use the smaller plain nuts to hold the spacer/adapter to the axle or hub.
Also make sure that there is nothing between the spacer and hub. On the disc brake axles there was originally a small serrated washer on one of the lugs on each wheel that needs to be removed if it's still on there before installing the spacer.

Just like LJDave said. Also put some anti-seize on the threads. Torque accordingly.

Well I tore up my garage and managed to find 15 lug nuts I could tear the caps off of, so I can get 3 wheels to look like this. I'll have to go find some more at an auto place. The next problem is keeping the front rotor locked while I tighten the lugs on the adapter. I know there have to be several dozen people here that use spacers, so same principle. Did you guys use recessed lug nuts and how did you lock the front rotors to torque the lug nuts?

Thanks. Does it matter if I use the smaller nuts or the acorn nuts? Like I said, I could only find find 15 smaller ones after digging and I'd have to buy 5 more for 1 wheel. Are they a necessity? Does the face of the adapter need to be absolutely flush with the inside of the wheel?

You need to make sure that the tapered lug nuts do not interfere with the wheel. Normally, the lug nuts holding the spacer onto the axle do not stick up higher than the face of the spacer.

Dang. The ones I found and put on stick out maybe 1/4 inch. Is that going to interfere with braking or what? I'm not sure how that affects the wheel if the face of the adapter/spacer isn't flush with the inside of the wheel.

And dammit, Walmart doesn't sell lug nuts, gonna have to hit the auto supply places tomorrow.

The lugs holding the wheel adapters MUST be flush with the spacer. They cannot exceed the spacer width, otherwise they will interfere with the wheels when bolted on.

Here are mine, they are flush:

You need tapered nuts hold the adapter properly. Nothing can stick out past the face of the spacer. Most spacers come with the correct nuts. Use an impact to tighten them, or have someone hold the brakes on.

The nuts on the adapter must not interfere with the wheels, but strictly speaking they may stick out with certain wheels. Many wheels have cavities on the mounting surface of the wheels in between the holes (to deal with shrinkage issues in the casting process), for example:


I don't remember if JK wheels are like this and can't find pictures of them, but if the wheels you are putting on have these recesses, you MAY be able to get away with the lug nuts protruding a little. The wheel MUST mount flat to the adapter though.
