I managed to put the Energy suspension units on today, and a couple things I noticed. Both of the zerks were cross-threaded. Managed to get them to work by pulling them out and cranking them back in. I also noticed that I think these bushings are probably 1/8 to 3/16 inches too small of inner diameter. At least for me, when put around the bar, the insertion gap in the slot was at least 1/8". This of course closed when I cranked them down a lot but I'm concerned that this much resistance may actually cause them to wear down faster than they should.
we'll see if they are any better, but hope so.
