4.11's with 35" tires will get you almost exactly back to stock gear ratio. The 4.56's would be one plus which I highly suggest. I did 4.11's in my truck with 5" lift and 35's and really wish I had done the 4.56 and maybe even the 4.88. With the big tires and OD, it won't hurt a thing, especially if you tow a lot.

I don't tie a whole lot every now and then. But sometimes my transmission feels like it shifts to early. Guess I'm gonna look into 4.56 gears and a tuner and see what that does for me.

It is shifting early because you don't have a programmer to fix the speedo. The transmission shifts based on speed. With the pump thinking it has a different size tire than factory the speedo is slow.
