Is atvr the only place that sells these?Ihave purchased two from niel already and both have come loose even though they were installed correctly.atvr accuses me of installing incorrectly,total b.s..The d was alined and the bolt was torqued down to 80lbs.They say if you install correctly the bolt will NEVER come loose,total b.s..My first one lasted about 20 hours,second one 3 hours.These clutches need to be checked constantly for loosening.Anyway,I am extremely disappointed with atvrs poor customer service,instead trying to work it out with me they just accuse me of incorrect install and thumb there nose at my legit complaint.I have spent several thousand bucks at atvr and have been pretty happy with them in the past but they are really dropping the ball on this one, not sure I want to do business with them anymore.
