A Dependable Solution. So, you've added an airbag system to improve the ride quality and load carrying capacity, but you don't want to lose your suspension's full travel.

This kit is designed to work with any convoluted airbag with a 4.11" or smaller diameter, providing more room for the airbag to cycle safely. Made of glass-reinforced nylon, this kit is tough and durable.\Installation and Warranty. Our Universal Air Spring Cradle Kit easily installs to the lower air spring mount; however, some applications may require drilling. Since it's backed with a limited lifetime replacement warranty towards manufacturer defects, you can be sure that you're getting a quality product. Our industry-leading warranty will give you peace of mind when using Rough Country's products!
