Air bags

Looking to see if any one has done an upgrade to their suspension on a Aria 3601. Or maybe even added an override to put more air in the air bags when you come to deep dip on a entrance to a driveway.
Feel like the suspension is lacking some support.

Weezly,


Welcome to iRV2.


With your Freightliner air suspension, the first steps are to verify that your suspension is at DESIGN RIDE HEIGHT.

Also, that your tires are properly inflated for your actual weight.

You don't mention age or miles, but make sure all suspension components (sway bar bushings for example) are in good condition/no play.


One of the most common first upgrades is to replace the shocks with better ones. Koni's speced for your chassis are well regarded.

Side roll as you enter a curb cut with a dip or rise is always a challenge for a suspension and air suspensions seem harder to control than spring in that regard.


Generally you shouldn't just adjust the suspension higher/firmer because it changes the drive shaft angle at the rear, basically putting the drive shaft out of alignment. Manual systems that let you override are to be avoided because a moments forgetful ness in resetting to auto-air management can lead to serious and expensive damage.



Motorhome air systems are already self-leveling and auto-adjusting, but they don't react quickly enough for a turn into a dip or rise. Something like the Comfort Ride air control valves might help your rig get thru those situations without any negative effects elsewhere.

Not sure if you have it, but air leveling usually has a manual leveling option. I push and hold all corners rise and gain several more inches of ground clearance. Works fine at walking speeds.

DITTO on what wolf and RVRoamer said. The Koni shocks for the better rebounding and air valve like the comfort ride for rapid air transfers side to side.
