How easy is the air suspension to maintain?

Our air suspension requires very little maintenance. We use the highest quality components like brass Parker fittings, Firestone bags, and Viair compressors. If you need to make a repair, many of the components are easily found at your local trailer repair facilities.

Lift Axle Option

We are very excited to introduce a lift axle option for air suspension equipped trailers. Most people are familiar with lift axles from their popularity in the semi-trailer industry.

Key benefits of the lift axle option include:

  • Reduces unnecessary tire wear when hauling empty
  • Improves the turning radius of trailer
  • Reduces lateral tire wear and "scrubbing" when turning
  • Axle can be lifted when traveling empty on toll roads to reduce tolls
  • Fuel Savings
  • Option Code: L (10,000 w/ electric brakes air ride lift axle would be axle code "A2BL")
Note: You must order at least a 6" axle spread to have a lift axle
