Question:
I purchased the SSR-106-54-1 Rear Helper Springs. I have a 2022 Thor Vegas 24.1 Ford E-350 Chassis. When I went to put the springs on I noticed on the drivers side that there is a vertical bar that is in the way on one of the bolt holes. I have seen other people with the same problem. Do you know how to mount these with this problem?

Expert Reply:
Hi Brett; the reason you are running into trouble is because the # SSR-106-54-1 does not fit Thor motorhome models for that E-350 chassis. Did you order these through us? I don't see an order under this email but you will need to return them to whoever you ordered them from. We have this listed in our tech notes as seen in the picture below. The only option that doesn't have the Thor motorhome restriction is the SumoSprings Solo Custom Helper Springs # SSR-130-54.
