Rite-Ride 4189 - Manual (Page 2)

STEP 1—VEHICLE PREPARATION
Remove the negative battery cable. With the vehicle on a solid level surface, chock the front wheels. Using a jack rated for the
weight of your vehicle, raise the wheels off the ground. Lower the vehicle frame onto jack stands rated for the vehicle weight,
making sure the suspension is fully extended. (Do not use wood or concrete blocks to support the vehicle.)
STEP 2—REMOVE THE COIL SPRING
Put a jack under the axle on the left side of the vehicle. Remove the lower bolt from the shock absorber. Lower the axle until the
coil spring can be removed. Caution: DO NOT put tension or strain on the flexible brake line. Remove the jounce bumper
located in the coil spring. The jounce bumper will not be reused. Drill a 3/8" hole in the center of the lower spring seat for the air
line to pass through. See Figure “C”.
STEP 3—INSTALL THE AIR SPRING
Deflate the Coil-Rite air spring and place it inside the coil spring with the air fitting pointing down. Next, place the protector on
top of the Coil-Rite for vans, or on the bottom for cars (Figure “A” & “B”) . Cut the air line into to equal lengths, making sure
the ends are cut as squarely as possible (a “sawing” motion with a razor blade is preferred). Route the air line through the hole
in the lower spring seat and along the axle. Push one end of the air line into the fitting on the air spring.
STEP 4—REINSTALL THE COIL SPRING
Reinstall the coil spring with the Coil-Rite on the vehicle. Pass the excess air line through the hole drilled into the lower spring
seat. Reattach the bottom of the shock absorber and tighten the bolt to manufacturers’ specifications. See Figure “D”. Please
see heat shield notice for installation of heat shield.
For installation on the right side, repeat Steps 2 through 5.
STEP 5—INSTALL THE INFLATION VALVES
Choose a location to mount the inflation valves, this should be a protected location such as the rear bumper. Drill two 5/16”" holes
and pass the valves through and tighten the nuts. See Figure “F”.
STEP 6—ROUTE THE AIR LINE
Route the air line from the air springs to the inflation valves (Figure “E”) . Avoid any sharp edges or hot surfaces as well as
sharp angles. The air line can be secured with the nylon ties provided. Cut off any excess air line using the method mentioned
above and push the end as far as possible into the inflation valve.
STEP 7—INFLATE AND TEST
Inflate the air springs to recommended maximum operating pressure (see page 1 for operating pressures). With a soap and
water solution, check for air leaks around the fittings and valve core. Inflate and deflate in small increments to find the ideal riding
conditions for your vehicle.
STEP 8—COMPLETION
Raise the vehicle, remove the jack stands, and lower the vehicle to the ground. Reattach the battery cable.
