I wanted to be able to adjust the preload on my 2020 KTM 690 enduro. Tapping on the adjuster screw a couple times felt dangerous as the stock adjuster is plastic and was getting trashed with a couple taps. Went to a suspension shop and they did not have a tool that could reach in, so I ordered an Xtrig preload adjuster. I had the shop install it and they said it went on perfectly. They have installed many of them. When I went in to adjust the sag, we only got a couple turns out of the Xtrig before it started to seize up. We tuned it the other way and it seized up again. We were using an impact driver. Unhappy with the resistance to turning we decided to take things apart. When we got the shock off, and the spring off, the xtrig was still frozen. All we could do is cut the darn thing off. Upon inspection we found a big chunk of the shock body thread imbedded in the threads of the xtrig.. Obviously a thread war had gone on and the xtrig won. Unfortunately I was screwed. I tried to get the vendor to send me another one and they refused, sending me to the distributor. The distributor wanted to see the pieces so I sent them in. Of course they claimed it was not their fault, and tried to blame the installer. They think my shock threads were bad to begin with, or the installer stripped it going in. I doubt either of those as the bike is almost new, and the installer was experienced. We plan to replace the threaded body of the shock, and I'll buy another xtrig, but I cannot figure out what happened to me. Has anyone else had an xtrig trash their shock threads?
