Very interesting guys, I had a snapped hook this week, on my ion Radar seat harness, You can see from the top shaft it looks like it's been rusting a while, and I will confess I'm not the best one for rinsing every time, will do in future!! But harness aprox 1 year old, so I will go back to where I purchased it, but all these comments make me think I should try a different brand, shame as the radar is very comfortable, I probably stressed it boosting as I'm not the lightest.
my welding friend said that as the bend is so near the weld, heating up the metal would create a possible weak spot in that location, and that's where the bend is.
I tried to replace the hook but two of the captive nuts have come away so now it needs the whole spreader bar assembly.
We do put our gear through some pretty rough treatment and I will give this part to the dealer who can give feedback to ion so hopefully can address any future weak spots.
