1. Raise car to a safe comfortable working height. Support the car with proper jack stands under the
body of the car to let the axle hang freely.
2. Disconnect shock absorbers to let the axle drop far enough to remove coil springs. You may need
a floor jack to support the axle as the shocks are removed. It may also be necessary to remove
the brake line bracket to allow the axle to drop down.
3. Apply thread sealant to a straight air
fitting and screw it into the top of the air
spring.
4. Bolt the upper cup bracket to the top of
the air spring and secure with two 3/8”
Nylok nuts and flat washers.
5. Screw the 7/16” all thread into the nut
in the bottom of the cup.
6. Place the air spring assembly into the
coil spring pocket with the stud sticking up
through the frame. Slide the retaining
plate through the hole in the frame rail and
over the 7/16” stud. Use a 7/16” Nylok
and flat washer to clamp the air spring
assembly to the frame.
