Hey all , I just wanted to share an experience I had with Perfex Industries. They have a lift kit for the U800's and I installed the kit last year. Easy to install and with the recommended spacers, it didn't change the way it handled. The reason I am talking about them is I recently had my 2021 serviced and the tools that worked on it stripped the threads on the rt front spacer studs and denied it was them that did it. I contacted Perfex to see what my options were to get me back to a safe unit. I was looking to see if I could get studs and replace myself. Fred from Perfex reached out to me and told m he will send 1 new spacer at no cost!! Including shipping!! Who does that nowadays?!?! Anyway, I just wanted to share a positive experience with a vendor that goes above and beyond. Kudos to Fred and Perfex Industries!! I have no affiliation with them other than being a satisfied customer.
