Bellows Ultimate Features

Discover the key benefits of Polyair Bellows Ultimate, designed to enhance your vehicle’s performance and comfort.

Added Peace of Mind

Unlike the standard Bellows air bags, the Bellows Ultimate feature an internal bump stop. 
This addition gives you added protection for those really heavy loads. 
The bump stops gives you peace of mind that the air bags can handle any unexpected challenges. 

Adjustable Air Support

The Polyair Bellows kits offer air adjustability from 5-100 psi, allowing you to tailor the level of support for different load types and weights. This ensures a comfortable, smooth ride when unloaded and optimal handling and safety when carrying heavy loads.

Durable Construction

Built with superior 2-ply fabric reinforced rubber and ultra-high strength, corrosion-proof Zytel® Nylon end caps, Polyair Bellows are designed for long-lasting performance and reliability. Easy to install with illustrated instructions, these kits often do not require chassis drilling for most applications.
