Went to take the suspension system out of a 2006 mxz 600, custom built and I'm quite positive it isn't a stock mxz suspension system. Went to loosen the track adjuster bolts and they would not budge. Even with an impact gun, they would not move and ended up snapping one of the bolts. Is this a normal problem with this certain suspension system? Pulled many suspensions out before and never had this issue. Any tips would be greatly appreciated.
