Only Cub Cadets - Super Steer Axle Question

I have a 1512 Diesel Cub that I removed a 50" deck and placed a 54" later model tall deck on along with the hanger for it and used the 1512 mule drive. Has 12x12x24 rear tires (zero turn size) so the tractor sits just a little higher in the rear. Deck fits fine, mows fine, clears front and rear tires even when turning. Issue is when I raise the deck the rear will lift 1 1/2" and the front only about 1/2". I adjusted the front of the deck all the way up. I could go to taller tires on the front although they might hit the deck when turning. I have a Super Steer axle that I was considering installing that will move the front wheels forward although I don't know if it will raise the front of the tractor up. I measured the distance between the center axle pivot bolt and center of the spindles outer tip and both the Super Steer and the stock axle are the same 4". I have read several articles here with some stating it will raise the tractor 2" and others saying it will be the same height. Also some mentioned a difference between the 1861, 1862, 1863 & 1864 although when I look up the part numbers through Cub Cadet they show the same axle and spindles part numbers for all 4 models throughout their productions years. So my question is am I going to gain any front end height along with mower raising height changing axles with them measuring the same 4"? I know the axle will move the tires forward but that is not necessary.
