2021 Sierra 1500 AT4 w/ 3.0L diesel. 
5100 front and rear with Cognito UCA (tubular ones). Front 5100 set to max 1.1” (AT4 specific 5100’s)

stock 18” wheels and Duratrac 275/65r18 tires

 

It’s pretty level but I can tell from eyeball it isn’t exact. No rubbing from the tires on the UCA’s. Ride seems improved so far but it’s only been a day. Going on a trip this weekend so I’ll have more time to evaluate.

Did you put on bigger tires with no issues? 
 

Thanks for the reply! 

No, I ran 275/60R20 Ridge Grapplers.  There seemed to be plenty of room for bigger tires though.  I want to try a 35x11.5, but haven't yet.

Yeah, that's what I'm contemplating. Was leaning towards 285/65/r20 ridge grapplers, but then saw 295/65/r20 on a AT4 and they looked great but they used a 1.75inch level on it. Cant decide. Dont want to go to heavy above stock tires also.
