Ridetech 19010999 - Manual (Page 2)

MII w/ Tubular style lower control arm
1. Assemble the airspring and upper mount into the suspension.
2. If you are using a tubular lower a-arm, a plate is used to provide a place to set the lower airspring
mount. Insert the lower plate and airspring mount between the top of the tubular a-arm and the
bottom of the airspring and attach the lower mount to the airspring.
3. Set the lower a-arm at the proper ride height. [level with the ground] There should be approx. 5” to
5.5” between the upper and lower mounts and they should be parallel and aligned.
4. Temporarily attach the plate to the a-arm and the lower airspring mount to the plate.
5. Move the suspension through its entire travel and steering angle to the airspring clears
EVERYTHING! Pay particular attention to things like brake hoses, balljoint cotter pins, and brake
calipers. Minor adjustments may be necessary.
6. When you are sure of the necessary clearances, you can permanently fasten the bracketry in
place.
7. The shock absorber will be mounted on the outboard side of the a-arm, usually on the rear side.
On the tubular lower a-arm, the lower U bracket is attached using the old shock bolt. The upper
mount is welded to the frame rail directly behind the upper a-arm. A single upper plate is used to
allow some latitude in the exact angle of attachment. Trial fit the shock to ensure that there is no
interference with any other suspension component.
NOTE:
We consider ride height on a Mustang II front suspension to be when the lower a-arms are parallel
with the ground. From this point, you will have approx. 4” of drop available when the airsprings are
deflated. Keep this in mind when considering ground clearance.
