Air Lift Suspension

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
