Polyair Bellows Ultimate

The Polyair Bellows Ultimate range is a load assist kit for leaf sprung vehicles, providing adjustable air support to prevent rear-end sagging when loaded or towing. It suits drivers who carry heavy loads or tow, delivering a smooth ride unloaded and better handling under weight. Built for both standard and raised applications.

• Air adjustable from 5 to 100psi for any load
• Internal bump stop for heavy-load protection
• Superior 2-ply fabric reinforced rubber construction
• Corrosion-proof Zytel Nylon end caps
• Smooth ride unloaded, better handling when loaded
• Easy to install with no chassis drilling on most applications

Unlike standard Bellows air bags, the Ultimate features an internal bump stop for added protection under really heavy or unexpected loads. Optional Polyair Cradle Kits let the bellow detach at one end so your suspension can fully extend, improving articulation and grip off-road. Wireless compressor kits are also available in single-path and dual-path configurations for on-the-go inflation via handheld controller or app.
