Adjusting Ride Height
The proper Ride Height measurements are: 6 ½"
front and 8" rear. Ride heights should be within ¼".
To adjust the suspension ride height begin with:
• The motorhome on flat level surface.
• Air system fully charged.
• Suspension at normal ride height.
Start by checking the distance in the front.
1. Measure the distance between the mounting
plates of the air springs at the centerline of the air
spring.
2. If the measurement is off, loosen the adjusting
lock nut at the eccentric slot on the valve.
3. Move the plastic arm up to raise suspen-
sion height and inflate the air spring. Move
the plastic arm down to lower suspension
height and deflate the air spring. Make
adjustments in small increments.
4. After obtaining the specified distance,
insert a 1/8" or 7/64" inch twist drill bit into
the plastic arm and valve body. This will
center the travel of internal piston. Tighten
adjusting lock nut between 60 - 80 in/lbs.
5. Check adjustments made by using the Air
Dump switch to deflate air springs. Start the
engine and allow the air system to become
fully charged. Allow the suspension to
adjust and come to a neutral setting.
6. Re-check the suspension height measure-
ment. Follow the same procedure for each
rear control valve.
7. Re-check the front suspension height after
adjusting the rear height control valves.
NOTE:
Do not modify length of the linkage rods. Make any necessary adjustments using
eccentric slot on the ride height control valve.
Once set correctly, the ride height setting should not change, except in the case of a component fail-
ure. This is usually characterized by one end of the motorhome sitting unusually low or high. In the
event this occurs, it is not advisable to drive as body or suspension damage may result.
