Airbagit Air Kit - Manual (Page 10)

Make sure the upper and lower brackets are in relative alignment,
and make sure there is not body or metal contact when the bag
travels up/down. Trim, move, or do whatever is necessary.
We design the brackets so ride height is 3” below factory level. This
is the “SweetSpot” to get a smooth ride. If you raise or lower the
vehicle more than 3”, the ride quality will change. The correct way is
put a metal spacer to raise the ride height, or shorten the bracket (if
possible) to go to the lowest possible position. Depending on how
hands on you are, you can install this kit yourself with no problems.
Rear Shocks and Shock Relocaters should be considered if you have
to move your shock absorbers. In any event, Shorter Shocks should
be installed at your option. Install Instructions are on the attached
.pdf file below.
