Dare to ask?

So, the 3" lift really won;t be a "true" 3" lift. The truck will settle a bit after the install. The Truxx kit is very close to what you just got....if I was looking at the same from Ebay.

IMO, I would put your 3" kit on, and go to your tire shop and see if they can do a test fit. 37's "could" rub depending on the overall width of the tire (12.50 vs 13.50) and rim with a higher offset. I had the Rancho kit ("4 kit") with 37 13.50's and just barely fit at full flex. Now, on that kit, it was higher than 4"...closer to 6" in the front. The tbars were cranked up too high though and was getting huge vibration from the front end. The same may happen if you crnak up your new keys too high.

IMO, put the 37's on with the rims you plan to run down the road with the higher lift. Than when you do go up, add the 40's in that you plan to do. I think you'll be happyu with the look/ performance on 37's and you won;t have to regear at this point. Plan to put a programmer on with your 37's and you won;t even notice the power decreasing from the larger tires.

...my 2 cents. BTW- I plan to run the TRUXX kit with 37 13.50's. I have seen the setup in person on another truck (same height) and the 37's just fit when flexed up. This guy is running 37 13.50 18 toyo mt's on 18" Rockstars. Looks huge!!!
