Recommended Suspension Enhancements For A 2013 Thor Challenger 37KT Class A Motorhome

Question:

I have a 2013 Thor Challenger 37KT on a Ford F53 chassis that needs suspension help. When I look through your website the choices for compatible parts is dizzying. How do I find the right parts?

Having worked in our installation department I can say that the most preferred suspension enhancement for a Class A motorhome is definitely SumoSprings. They provide a much softer progression to give you support without sacrificing ride quality. The best part of these springs is that they are completely maintenance free so you won't have to do anything else once they're installed.

For the front of your 2013 Thor Challenger 37KT I recommend the SumoSprings Rebel Custom Helper Springs # SSF-173-40-2 and for the rear I recommend the SumoSprings Maxim Custom Helper Springs # SSR-187-54-1.

I've attached some videos below where Dave will walk you through the installation process if you choose to do this yourself.
