Suspension Guide: The right solution for more payload, comfort, and ground clearance

Find the right suspension solution for your vehicle


Whether it's a motorhome, van, pickup, SUV, or truck – the right suspension solution ensures more driving comfort, higher payload capacity, better handling, and increased ground clearance.

Many vehicle owners are familiar with the problem: the motorhome sags at the rear, the van drops when loaded, or the pickup reaches its limits off-road. But what is the right solution?

In this guide, you will learn when auxiliary air springs, reinforcement springs, or lift kits are the best choice for your vehicle and what advantages each system offers.


Auxiliary air spring, air suspension or air ride system – what's the difference?

Various terms are often used:

  • Auxiliary air spring

  • Auxiliary air springs
  • Auxiliary air suspension
  • Air spring
  • Air springs
  • Air suspension
  • Air ride system
  • Rear axle air suspension
  • Air bellow
  • Air bellows

Most often, they refer to the same solution: an auxiliary air suspension system supports the vehicle's standard suspension by using air bellows between the axle and the chassis.
