Sumosprings on Thor Challenger

I just had Sumosprings installed on my 2016 Thor Challenger 37tb. This modification really helps helps when big truck pass and I immediately noticed it feels like I have more control at the wheel. So far, I think this was a wise investment of about $1,700 for from and rear Sumosprings installed. I just returned from a 1,200 mile trip of the Northeast and the Sumosprings worked great.

I'm installing the front sumo springs on my F53 soon.

I'm on a quest to locate softer leaf springs. Changing out the front leaf springs, in my view, will give the F53 chassis a much softer ride. They are just too stiff.
