Polyair Spring Suspension

Polyair Ultimate Air Bellows

The Polyair Bellows Ultimate load assist kits are specifically designed to suit big American SUV’s and 4WD’s. With an internal bump stop to help absorb shock, even with zero air pressure, it provides a three-stage ride comfort.

They are ideal for large American 2WD and 4Wd trucks such as Dodge, Ram, Chev 2500HD, GMC 2500HD, Ford ‘F’ Series and Toyota Tundra.  Also suitable for large caravans, 5th wheelers and heavy horse floats.

The Polyair Ultimate Bellows are rated at 2,800KG and can be used up to 100 P.S.I. They have separate airlines to each bag to stop sway and give better handling and ride control under all types of road and off-road conditions.

On the Ram utes they fit beside the coil springs, and with all other utes they fit between the rear axle and chassis.

They are ideal for use with air inflation kits including the popular Polyair Wireless Remote Compressor Kit.
