Any 2.5" UCAs that wont rub tires without offset wheels/spacers?

DutchOvenTheTruck · March 10

2018 Silverado 1500 LT
2.5" in front and 3" in back
Bought Rough Country UCAs and they rub at full lock
I have 20"wheels and 32" tires
Trying to avoid both spacers and new wheels/tires

Has anyone come across UCAs that will not rub the tire with a similar setup?

I went with MotoFab Ucas: Motofab 3" front and 2" rear lift with 35x12.5x18 BFG KO2s but still had to put on 1/2 inch spacers.
I doubt you can get around this without a knuckle extension.

I appreciate the response and like your nightlight solution. Can you elaborate on a knuckle extension? That is new to me. Also, which 1/2" spacers did you go with? I found some 15mm billet hubcentric spacers on Amazon with decent enough reviews.

I have a set of the 15mm spacers with the ET (extended thread) lug nuts that I use with my stock wheels in the winter just to push the tires out a little. I don’t need the spacers for clearance. I have Superlift upper control arms. They appear to have the same wheel and tire clearance as the factory aluminum arms.

Do you happen to remember which 15mm spacers you got? Appreciate it.

I believe I bought them from Ready Lift but it's been awhile .
For more information about a knuckle lift, here is an earlier post from here:

Same ones I ordered. I appreciate it! Any issues with these at all? In your video it says you didn't need extended lugs, but you mentioned you're using the ET lugs that came with the spacers. Unless I heard you wrong. Thanks again.

You’re welcome. They are a snug fit into the bore of my factory wheels. I tapped them in with a soft dead blow hammer. I wouldn’t feel safe using the spacers without the ET lug nuts.

My mistake I thought that was your video. You know, I don't have factory wheels so I had to return mine. I've got aftermarket spacers from the same seller coming in. The others did not fit, but you're mentioning tapping them in. The thought DID cross my mind but I was not sure if that was the play. Glad you mentioned that.

The spacers are the same for factory wheels and aftermarket. The lugs are different though. The factory style ET lugs have a larger shoulder diameter and larger hex size. They won’t work with my aftermarket wheels either.

Ah, so the spacers don't fit yours either? Did you find another solution/workaround? Maybe you already mentioned it but I may have missed it.

The spacers will fit, but the stock style lug nuts won’t fit through the smaller holes in my aftermarket wheels. They make different lug nuts to use with aftermarket wheels.

Strange. I ordered the factory style spacers from the same people and I could not get them flush. Thanks again for all the feedback.
