Symptoms such as:
Suspension bottoming out
Rough ride
Excessive sway & body roll
Unpredictable braking characteristics
Poor headlight aim
Clearance issues

Benefits of the Bellows Kit:

Maintains proper ride level for heavy loads Renews life in tired springs Adjustable to suit the relevant load Makes vehicles safer to drive when laden

All this can be mitigated by installing a set of Polyair Bellows. The Bellows kit is air adjustable giving you flexibility to tailor the level of support for your individual load types and weights.

Having a correctly sprung vehicle for constant loads is always recommended as the first step, but in most cases the leaf springs are rated well past what you will carry daily, giving you a rough, uncomfortable ride when not loaded up.

Having the flexibility of the adjustable Polyair Bellows means you can have a smooth stock ride comfort when unloaded and simply adjust the pressure when towing or hauling. Simple.
