Polaris did 2 inches and it worked wonders compared to the pro but I thought they said the axys motor sat the same amount off the ground as the pro motor. You don't change anything if both go up the same. In doing this there will be no change to anti stab wheels or rail pressure. The only change will be ride height. Big win in my book. Don't know where the ride height works against you. That is a trial and err thing.
