i recently purchased a set of denton a arms +2+1 with heim joints and after 10 hours use the top joints are stuffed,there is more play in them than a child care centre, what a heap of crap. why make somthing so exposed to dirt sand mud ect and not make a rubber boot for them. the dealer who sold them to me said they would last years, all you have to do is wash em after every ride and spray them with a little lubricant and she,ll be right. maybe if i rode around my lounge room and never took it out side they would be ok, so now its going to cost $50 bucks per joint.thats $200 aus dollars every 10 hours racing just in heim joints.so im off to buy a set of ball joints to replace them with.any one who is thinking of buying a arms with heim joints think again,i have no problems with the a arms there good and have heaps of adjustment , just a let down with those joints.
