I get that! I understand your scepticism. We've been using the swivel shock mount on our other kits for 3 years now with out one failure. Ive been using the swivel kit on our test sleds for 5 years with out a failure. The tweaks are nothing more than visual.
Ive never gotten any sand or grit onto the swivel area. And we ride some pretty gnarly stuff. The main reason we went with the swivel mount is that the kits that were out at the time (not going to mention names) used the spherical bearings in the shocks, from what we saw and the units we rode. The shock was constantly binding and being put under strain. We didn't like what we saw.
We really try to beat up our product when we are out testing. We personally test our stuff.
We stand behind what we sell.
If you run into a tree and break something well then its on you.
But if one of our kits fail, we will replace it.
