Some answers to the most frequently asked questions by our customers.

  • Q. How much do they cost?

    A. Polyair Springs are excellent value, being the most economically priced suspension aid product on the market. They frequently are lower in price than replacement or overload springs and air shocks. Since price varies with application, refer to the current price list.

  • Q. Do I have to remove my springs to install them?

    A. The Polyair Spring is a suspension add-on to original equipment springs. Some kit numbers will require temporary removal of spring for installation.

  • Q. Will they raise my vehicle?

    A. Original equipment springs tend to sag from wear or from overloading. Each Polyair kit is designed to level the vehicle to the original designed height with up to 500kg of load. Some vehicles can be raised an additional 25mm when inflated with maximum air pressure and carrying minimum load.

  • Q. How do I fill them and how much air do I need?

    A. Due to low air pressure requirements, Polyair's can be inflated using a hand pump or service station hose, as you would fill a tyre. All kits include air hoses for easy inflation of dual air valves.

  • Q. What is the warranty?

    A. Polyair's have a 24 month, unlimited km warranty. Any defective part will be replaced free, provided the kit has been correctly installed and correct inflation pressures have been adhered to.

  • Q. Will they affect the ride of the vehicle?

    A. The ride can be tailored to meet the driver’s personal comfort by increasing or decreasing air pressure. If air pressure is increased in proportion to the load, ride quality should not change.

  • Q. Will the rubbing action of the coil spring on the Polyair cylinder cause it to wear out?

    A. Polyair's are made of a highly durable urethane material, which has outstanding wearing characteristics in desert-hot to sub-zero temperature extremes. When properly inflated, they will provide years and years of trouble-free service.

  • Q. Do I have to change my shock absorber?

    A. Not if they are functioning properly. In fact, Polyair's will actually increase the life of the shock absorber.
