Polyair Ultimate

The Polyair Ultimate Series is a range of in-coil load assist air bags for coil sprung vehicles. It provides adjustable air support to prevent rear-end sagging when loaded or towing, making it well suited to those who regularly carry heavy loads or travel fully laden.

• Air adjustable from 5-60psi to suit any load
• Prevents rear-end sagging when loaded or towing
• Smooth ride when the vehicle is unloaded
• Tough moulded polyurethane construction for durability
• Suits standard and raised coil sprung applications
• Easy to install with illustrated instructions

As Polyair's highest rated in-coil air bag, the Ultimate Series uses a special polyurethane construction that supports high pressure load levelling. Optional wireless compressor kits are available in single-path and dual-path configurations, allowing you to inflate and deflate on the go via a handheld controller or mobile app. Dual-path systems provide independent control of each air spring for uneven loads.
