Well, my Autozone Mighty-Lift D95004 finally got weaker just over a year after install. Plus as I mentioned above, I heat wrapped them to protect them from engine heat. It still let a little heat onto them, but sure cut it down quite a bit. They have been a little weak in the CA winter (with CA temps around 50-60 during the day), but now that we are experiencing warmer weather, it seems they are still weak. So, I thought I would just report back that my heat wrap experiment didn't quite work in keeping them strong. So now I just use the clamp-on devise onto one of the struts to keep it up. I may actually go back to the Detomaso 18126A that the vendors are selling, eventhough the pressure I tested seemed high as noted below. But if no one has issues with them being too strong, then what the hey, strap em on.
Detomaso 18126A pressure: 1/2 to 1" compressed = 120 lb (this is what it took to make it start to compress).
2" to full compression gradually increased from the 120 to 160 near full compression.
