Chassis Guide: The right solution for more payload, comfort, and ground clearance
Finding the Right Suspension Solution for Your Vehicle
Whether it's a motorhome, van, pickup, off-road vehicle, or truck – the right suspension solution ensures greater driving comfort, higher payload, better handling characteristics, and more ground clearance.
Many vehicle owners know the problem: the motorhome sags at the back, 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, heavy-duty 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?
Different terms are often used:
- Auxiliary air spring
- Auxiliary air springs
- Auxiliary air suspension

Reinforcement springs increase the vehicle's load capacity and prevent sagging under heavy loads.
