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 of the top of the front wheel opening

on the fender to ground, this is height H1.

3. Attach the trailer to the vehicle without the weight

distribution bars connected.

4. Measure the height of the top of the front wheel opening

on the fender to 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. Preform a visual inspection of the trailer and weight

distributing hitch to confirm manufacturers’ recommen-

dations have been met.
