Helpful Expert Reply:

The best way to enhance the ride of your 2018 Thor Axis, which was built on a Ford E-450 chassis, is to add a rear anti-sway bar. After that you can further improve the ride by adding a front anti-sway bar; the combination of these two parts will dramatically increase the handling and comfort of your Thor Axis, allowing you to enjoy your time on the road instead of exhaustingly attempting to keep your rig centered at all times.

The correct fit for your 2018 Thor Axis is the Roadmaster Rear Anti-Sway Bar # RM-1139-147, Front Anti-Sway Bar # RM-1139-176.

There is a way to improve the ride on your 2017 Mercedes Benz Sprinter 2400 with 4WD but there is not a fit for any type of air suspension kit, which is what I believe you are asking (as opposed to your Sprinter having air suspension). I recommend using SumoSprings Rebel Custom Helper Springs # SSR-327-40-2 for the rear axle and SumoSprings Solo Custom Helper Springs # SSF-327-47 for the front axle. Each of these are jounce-style springs that compress and absorb the bumps and shock, sort of like a sponge for your suspension. These springs are a simple bolt-on installation and will not require any maintenance after they are on your van.

For your 2017 Thor Axis 25.2, built on a Ford E-450, there is an air suspension kit available. I recommend checking out the Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88242, which can work on Class C motorhomes, so long as the distance from the outside of the frame to the inside of the tire is at least 8" and there are no obstructions, such as supply lines, on the outside of frame in the area to be installed. These airbags can be adjusted individually from 5 psi to 100 psi to help compensate for off-center loads and have a 4,800 lb load-leveling capacity. The airbags are going to improve your Thor's handling and reduce tire wear by helping keep your front tires on the ground and will also benefit your vehicle's rear suspension by preventing sagging. These are manually adjusting airbags though you can use the Air Lift WirelessONE Compressor System for Air Helper Springs # AL25980 which gives you a hand-held remote so you can adjust the airbags more conveniently.
