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. IMG_5060.thumb.jpeg.ccc1697ff196cd30081d4da87b84713f.jpeg

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.

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
