LOWERING THE SUSPENSION

It will be necessary to lower the suspension of the vehicle in order to provide clearance to

install the air spring unit (g. 6). The following are tips on lowering the axle or raising the

frame. Please review them and determine how to proceed:

1. If the vehicle is raised with an axle contact hoist, place axle stands under the frame and

lower the axle as needed.

2. If the vehicle is raised with a frame contact hoist, place axle stands under the axle and

lower the frame as needed.

3. If the vehicle is raised with a jack and supported with axle stands on the frame, use a

oor jack to lower the axle.

ATTACHING THE UPPER BRACKET

1. Unbolt and remove the rubber jounce bumper from the frame rail and discard (g. 7).

2. With the

/8 x

/8” hex head bolt (M) loose in the air spring, insert the stud through the

original jounce bumper mounting hole (g. 8).
