Just installed SumoSprings front and rear on 2015 Axis 24.1 yesterday. I went with SSF 106-40 (500lb) for the front and SSR 106-47 (1500lb) for the rear axle. I used my 20T bottle jack to lift the coach at 4 corners. Started with the front driver side as suggested by manufacturer. I thought that removing the wheel (which I did on that side only) will speed up the process but that was not necessary. The front of passenger side as well as the both rear side were done without wheel removal. Front is really easy to do as long you use 10mm long socket. The rear procedure is the same except you have to deal with brake line bracket (on the driver side) which uses the same bolt. On the rear passenger side the exhaust is right where the SumoSpring is going. No drilling required. Just pretty simple bump stop replacements. It took me longer to move around heavy jack, safely set it up and lift the coach by hand then to replace the bumps with SS.
Today, I drove the coach for about 20 miles and could tell the difference right away. Still soft ride (that is why I went with softer springs) but without any swaying, rocking from side to side. Very solid, car like drive. We had a very strong winds today but the coach was not affected by those at all. I drove entire 20 mile route using only one hand. Incredible. It was almost like driving my SUV. I am very happy with the results. After the installation, the height of the coach have increased by 1/2 inch. The only negative thing I have noticed is that the motorhome was slightly pulled to the right. Maybe this was caused by gusty winds? I think, I might need to get wheel alignment done. Will test this again. Can't wait to go on a longer trip.
