A while back there were some threads going around about these ASR Arms, complaints how they would fall apart during riding.. It's bolts & nuts so it shouldn't be a problem, just add loctite to secure everthing and should be good, way better than stock. And Elkas & Works are definately better than YFZ but I got YFZ's because it's a cheap fix. Also not all A Arms will work with YFZ shocks. Get ahold of Sanddragon on here, he makes A Arms to accomodate the YFZ shocks.
