Charlie HutchinsApril 29, 2021 at 9:39 am 5 out of 5 We want to thank you for the great sumosprings products. We installed them on our 08 Bounder and the changes were night and day. Better ride, handling, less sway etc etc. It rides like a different coach and we are extremely grateful. I would recommend sumosprings to everyone. And the installation was not bad at all. Did it myself in about an hour and a half. Thanks Sumosprings.
