Installed the 6112 a couple weeks ago on my AT4 with the 5.3. Coils settled to exactly 1/8" of lift on postion #5. 

How’s the ride compared to factory?

You can keep the factory wheels if you want. I went offset and it’s why I’m having clearance issues on the outside. It’s catching the ear where the mud flap bolts on. Only thing I can do is cut it...

You can push the tabs back some but yeah your about out of options. How’s is the ride with that kit?  It looks great.

 

Thanks.

What’s the outcome if I do?  Would a half inch spacer on top be the same problem or be better?

Can you share any pictures?  Does that kit allow you to retain factory wheels?

 

You would be better to do the fender wheel support bracket delete and pull back the liner than push your suspension angles even further.  I would think the cv’s would have a hard time at 4”.

Any rubbing at all?  Debating on this exact size and tire or 275/65/20.  

Yes lots of rubbing. I did all the fender mods without cutting metal to make them fit.

Did you happen to have these tires mounted before you put on the RC leveling kit?  I have a bone stock AT4 without a leveling kit, so I'm wondering if 285/65/20 will work.  TIA.

I’ll save you some trouble. I put this size on my Sierra with a 2” level and could hardly turn without major running. I ended up heavily modding the fender wells and made them fit  but it was a pain. I’d go 286/60/20 on a stock AT4

What kind of lift do you have?  Looks great.

[275/65/20 2020 Sierra]

I have the same truck and lift. 285/65/20 rub bad.  You will probably have minor rubbing with 275/65/20 since it’s still a 34” tire. I’d go 285/60/20 if I could do it again. 
 

let us know how it works for you. 

[New tires rubbing with 2” level, what size fits??]

They are the AVS ones, I had some trouble with the edges stopping the window so I super glued the edges in place in the channel and have worked great since. 
 

I am hitting that same bolt head so not much I can do except take it out I suppose. 

[2020 Sierra 1500 stock - bigger tires wanted, advice please!]

Your not gonna have a lot of options without a level or doing the fender support removal.  The gmc fender wheel is narrower than the Chevy and previous years. 
 

I am running 286/65/20 bfg at’s with both of the aforementioned mods and still rub.

I’ve got 275/65R20 K02’s on my Sierra with no rubbing. I’m running the AT4 lift though.  Your 2” level should have same effect though as far as tire fitment 

Thank you for the feedback, that is very helpful.  Do you mind sharing a picture?

[New tires rubbing with 2” level, what size fits??]

Need some help, I just installed 285/65/20 BFG KO2’s on my 209 Sierra with 2” level and they are rubbing the mud flap and back fender well bad. I removed the bracket and pulled back the fender liner but still rub more than I want. 
 

I think I am going to switch to a 285/60/20 or a 275/65/20.  Does anyone have experience with these sizes on a Sierra?  I want zero run and not willing to cut the mud flap. 
 

I appreciate any help.

Thanks, I like the look better than the stock tires.  I'd say they definitely made the ride a bit firmer which I don't mind (coming from 24 years in a F-350 running an assortment of MT's and All - Terrains).

I didn't think about going with the 285/65's, I just played it safe with the 275/65's knowing they would fit.  If 285/65's fit with out rubbing, I could see myself going that direction next time, I think it would look better with a little more width.

Just got 285/65/20 ko2’s on my Sierra with 2” level and they rub the rock guard bad. Think I’m going back to stock size. 

[Tire size with level kit??]

I just put on 286/65/20 BFG KO2 with a 2”  RC level and it runs the mud flap pretty bad. 

[Mud flap removal]

Has anyone tried these?  Just put on new tires and rubbing right at the mud flap.

Yea I guess that would but dont want to go down lol had a hard enough time finding the 1" block so 1/2" is probably very hard

Where did you find the 1” block?

Here is the fender measurements, Bilsteins at max setting, 1.00 ebay rear blocks, and 295/55r22 Terra Grappler G2s.

 

Driver front - 39.00

Driver rear - 40.50

 

Pass front - 38.875

Pass rear - 40.50

 

Stock

Driver front - 36.25

Driver rear - 38.625

Pass front - 36.125

Pass rear - 38.625

 

Definitely a little more rake than I wanted. I may mill 25% off the height of the blocks to bring it down just a tad in the rear.

Your truck looks great!  Thank you for the measurements, looks like it was true to the claimed lift amount. Do you have a side picture to show the rake?  I plan to do the exact same to my Sierra.  
 

Thanks again.

Here is mine. 5100s at max setting in the front, with 5100s and stock height in the rear. I plan to add a 1” block to the rear. 295/55r22 Nitto Terra G2s. Slight rubbing at full lock on the liners. Need to do some slight trimming.

Looks great, thanks for sharing!  How is the ride at max height?  What is your fender height now?

 

Thanks again.

Thank you.  They are Callaway wheels.

What kind of lift is that?  Looks good. 

[Eibach Pro-Truck vs. Bilstein 5100]

Thanks for starting this thread, I am looking to buy one of these as well. 
 

Curious to know:

 

1. which ride is better?

2. which gives more lift without using the top setting?
3. what is the benefit of buying the new springs?

I did not see anyone respond to this question.  Would love to see pics of a non-TB/AT4 with the front 5100s set at the max height. 

Same here.
