Hi there!
Most likely, the rear damper doesn’t have enough droop, which is limiting the lift of the air cups.
I’ve just sent you an email with more information about this and how to solve it.
“Nice stuff. Everything you need is in the box.
Sad thing is the product doesn't match the drawing. Air tank is different then the drawing.
The outputs are on the top and for me that was an issue. Had to block of every port and make custom blocks for everything.
Pump is loud as hell to.
I still recommend the product”
Thank you for your review! You’re absolutely right about the drawing, while the tank dimensions were correct, the outlet ports didn’t match the drawing provided by VIAIR. We understand the frustration this caused and have flagged this with the supplier.
As for the compressor noise, it can indeed resonate if mounted directly to the chassis. Using the included rubber isolators can significantly reduce vibration and noise.
Thanks again for your review, and feel free to reach out if you need anything!
