Towing With 2500/3500 Air Suspension
Position the truck to be ready to connect to the trailer (do not connect the trailer).
Standard Ride Height (SRH) 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.
Measure the height from the top of the front wheel opening on the fender to the ground, this is height H1.
Attach the trailer to the vehicle without the weight distribution bars connected.
Measure the height from the top of the front wheel opening on the fender to the ground, this is height H2.
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 Standard Ride Height [H1]).
Perform a visual inspection of the trailer and weight distributing hitch to confirm manufacturer’s recommendations have been met.
Measurement Example | Example 2500/3500 Height (mm) |
---|---|
H1 | 1030 |
H2 | 1058 |
H2-H1 | 28 |
(H2-H1)/2 | 14 |
(H2-H1)/2 + H1 | 1044 |
For all towing conditions, we recommend towing with TOW/HAUL mode engaged.
