What is the purpose of the internal jounce bumper?

The internal jounce bumper replaces your factory jounce bumper. It helps prevent the vehicle from bottoming out, reduces squat and trailer sway, and works even if the air spring has no air pressure.

Can I run this air spring kit with zero air pressure?

Yes, the internal jounce bumper is designed to function even with zero air pressure in the air spring. This provides a baseline level of support and protection.

What is the warranty on this kit?

Air Lift offers a lifetime warranty on the air springs and hardware, along with a 60-day ride satisfaction guarantee.
