O alright so if I go over 3 in of lift I will have to do the high steer and a new driveline
Nope, none of the drivetrain is moved with a BL. That being said I would not put a 3" BL on my riding lawn mower, I have seen them break through the belly pan from the added leverage on the body mount bolts. Do not forget with a 3" BL you will need to also relocate your radiator, do something about your brake lines coming from the MC, re-adjust your e-brake,make your steering shaft longer from the colmun the the box, and get a longer flex tube for your gas filler.
