I installed front and rear Sumosprings on our Four Winds 24Hl. Which has a Sprinter chassis. Made a huge difference and well worth the money. The rear springs have a distortion as seen in the pictures. I contacted the vendor who then contacted Sumospring and a Sumo engineer said it due to the weight of the coach, "don't worry and they have a lifetime warranty."

They are still firmly in place and don't show any cracking or tearing. I have about 1000 miles on them.

Has anyone else seen this on the 3500 Sprinter?

Thanks for your help
