1. Raise and support the vehicle by the frame to the safe and comfortable working height.
2. Remove the coil spring and shock absorber. Refer to the factory service manual for proper
disassembly procedures.
****RideTech Shocks Required****
3. Remove the bump stop from the
frame and cut the upper convolution
off, then reinstall back onto the
frame. This will allow for maximum
drop.
Note: The bump stops must be
reinstalled to prevent damage to the
air spring.
4. The top of the lower coil spring
retainer must be cut off to accept the
lower air spring mount. A die
grinder with a cut off wheel works
well. Grind edges smooth.
5. Place the lower air spring roll
plate over the retainer.
6. Place the 4” washer on top of the
upper coil spring mount.
7. Screw the 3/8” x 2” stud into the
top of the air spring.
8. Slide the upper air spring mount
over the 3/8” stud. This mount is
required to fasten the air spring to
upper coil spring pocket.
9. Place the air spring into the coil
spring pocket with the 3/8” stud
sticking through the 4” washer.
Fasten the assembly with a 3/8”
Nylok nut and flat washer.
10. Slide the bottom of the air spring
over the coil spring retainer.
Note: The bottom of the air spring is
not fastened to the axle. Leave at
least 15 psi in the air springs when
lifted the vehicle by the frame.
12. To retain proper sway bar
geometry, shorter PosiLinks are
necessary. 12mm Nylok nuts are
suppled.
13. Ride height on this air spring is
approximately 9.5” tall. Depending
on vehicle weight this should occur
around 45 psi.
It is the final responsibility to ensure
that the air spring does not rub on
anything. Allowing the air spring
to rub will result in failure and is
not a warrantable situation.
