Built-In Jounce Air Springs
Adds Control and Comfort
The closed-cell urethane jounce spring inside each air spring gives you a more stable, comfortable ride. Each jounce acts as an overload spring and engages when your current air pressure level isn’t enough to support your load. So on a rough road, the springs will kick in if needed to absorb bumps and shocks and help you to avoid bottoming out. When the jounces support a load, they adjust progressively – the more weight you pile on, the stiffer they become. The urethane material engages more smoothly than rubber jounces so you get a less jerky ride.
