Towing With 2500/3500 Air Suspension
1. Position the truck to be ready to connect to
the trailer (do not connect the trailer).
NOTE:
Normal Ride Height (NRH) or Alternate Trailer
Height (ATH) can be used. The vehicle must remain
in the engine running position while attaching a
trailer for proper leveling of the air suspension
system. It may not be possible to enter Alternate
Trailer Height (ATH) while lightly loaded.
2. Measure the height from the top of the front
wheel opening on the fender to the ground,
this is height H1.

3. Attach the trailer to the vehicle without the
weight distribution bars connected.
4. Measure the height from the top of the front
wheel opening on the fender to the ground,
this is height H2.
5. Install and adjust the tension in the weight
distributing bars per the manufacturers'
recommendations so that the height of the
front fender is approximately (H2-H1)/2+H1
(about 1/2 the difference between H2 and H1
above normal ride height [H1]).
6. Perform a visual inspection of the trailer and
weight distributing hitch to confirm
manufacturer's recommendations have been
met.
