My SAW's were originally purchased in April, 2001, so they are the oldest version of SAW's out there. Scott Yoder's are probably the same original design. SAW has made several minor changes to their design - one of them being the threaded ring and how you tighten the screw to keep the ring from moving. Mine (and I'm guessing Scott's) have a vertical cut through the ring. They have a bolt that spans across the cut to tighten the ring around the shock so it won't move. Neither mine nor Scott's have seized. But this design can be extremely difficult to turn on the shock even when new, especially if you're pulling on the spanner wrench when it's in the hole immediately next to the cut in the ring. The edge of the ring seems to dig into the shock. But the cut in the ring seems to also be able to allow the ring to be pulled away from the shock body to prevent seizing.

Maybe 2 years ago, SAW started making the ring without the vertical cut, but instead with a screw that gets tightened into the threads in the side of the shock body. I know Darren has that newer design. It's significantly easier to thread higher when it's new. But I'm guessing maybe the newer design without the cut will seize easier? I don't know... just a thought.
