What is an acceptable clearance to the UCA?
With a readylift 1.75 level kit with upgraded UCA’s, 295 70 18 Falkens and 1/4 spacer I’m at 1/4” away from the tire. Thoughts? Thanks.

1/4in is probably ok. I’d check periodically for signs of the tire rubbing the UCAs.

I had the same size tires and same ready lift kit and had less clearance than you have. It didn’t rub at all but I decided to add 1.5in spacers to widen the stance.
 
Thanks- I May swap out the 1/4” spacers for 1/2” just to be safe.
 
I have 295 70 18 Falkens with the stock suspension. No rubbing and about 1/2" clearance with aftermarket copies of the 18" wheels.
 
Does anyone have a refreshed 2022 with duramax? I just picked mine up today. I tried to put 285/60R20 tires on and found they hit the UCA. With the stock 275/60R20 AT tires there is less than a half inch of clearance. I read tons of threads about 285 and even 295 tires on stock wheels without spacers. Curious if this is a 2022 issue or duramax issue or both. Without spacers I can't go wider than 275.
