Thanks for posting....

Brand new Barksdale and it's over inflating the airbags 🤦🏾‍♂️ do I tighten the nut on the valve once at dead band to set it in place?

[@calstatesammy]

What is the part number for the exhaust port valve? How do you replace just the valve? Please advise. Thank you.

Thx ! Helpful video

[@JoePJack1]

What about when the valve randomly adds air to the bags over inflating them.....dump the air and it returns to normal for a period of time and then repeats??

Did u happen to figure out your problem? I'm literally going through the samething. Just purchased my 4th valve for the year.

[@CrodDc5]

My steering will be fine and then get really loose causing oversteer from the bags being so over inflated after running for about and hour.
