They are maintenance free, do not leak air, and do not require airlines or compressors.

Very easy to install. Doesn’t affect my drive so far but I haven’t put the camper on yet to see if it helps my sag.

Arrived on time with all hardware. Box was beat-up but everything was inside. Install was pretty straight forward. Nothing negative report and did notice a strong improvement with trailer sway while towing, especially on the highway. Also bouncing recovery has improved.
