Looking for some feedback on this lift / tire set up

[SinisteRR]

Ive been searching for some solid information about my particular set up, and how it will function, so I thought id ask people who may know better than me. 

 

Currently, I have a 21 Silverado RST with a 5.3, 6 Speed, and 3.21's. I am looking to do this kit with a set of Nitto Terra Grappler G2's in 295/55/20. Essentially, the same as the photos of the Red RST on the Rough Country site. Ive done a similar set up on a previous truck and it worked well, but I had a 6.2L and 3.73's. Does anyone have a similar set up to my current truck and can give me some feedback on loss of power, loss of any towing capability, acceleration? 

 

I get that this set up is not ideal for a lift and tires, but does this size have a huge impact on performance? Thank you in advance for any insight.

I would look at other brands tbh, Rough Country suspension lifts don't necessarily have a good rep. Most complaints are ball joint related and how quickly they wear out. You can get a much better put together kit elsewhere. I used a rough country kit on an old Sonoma I built and it was ok but it had its issues with install and alignment. After looking at the UCA with that kit I kind of understood why the ball joint negativity exists. 

You should also keep in mind the CV axle angles with 4wd. 

Relating specifically to your concerns, the tire size shouldn't really impact your performance too much. It might slightly decrease your mpgs from the extra width of the tires and increase of aerodynamic drag from the lift, but the engine and drivetrain should be fine as long as the angles aren't too extreme
