...I thought We decided on the Correct Orientation of the Strut a Long Time Ago!!
The Rod Goes DOWN, so the Piston and Seals Stay Covered with the Lubricating Oil!! And YES! It IS The Heat that Makes Them Fail; as well as the 'Reservoir' being on the Bottom. With NO Lubrication the Piston Seals Dry out, can't Slide smoothly, they tear...NO more Pressure! There's No Mystery Here! And there's always the Heat! Even the Most Expensive Cylinders can Only Handle 140 Dgrees F! How hot do these Struts get? What is the temp Radiating off the Heads and Headers in the Vecinity of these Struts? 250F, 300F Higher?
I just finished Researching what I would need to produce a Custom, Fully Adjustable 'Air Strut', Specifically for the Pantera, and Only the Pantera! They are Perfectly 'Doable', But I would have to get $200. Each for them. And then they could only handle 140F Max.
I could Machine and build them from scratch, but the Piston 'Seal' would be 'Iffy'! and the cost would be Astronomical! Over the Cheaper Struts, there would never be a Market for Them!
My Advice is, if You mount them with the Rod Up, Expect them to Fail a Lot Sooner!! And even With the Rod Down, Sooner or Later, the Heat WILL Kill them! I suppose one could wrap a 'Ice-Pack' around them; or Install AC Onto them!LOL
Well, just use a Broomstick for a Hood-Prop and stop throwing Money away on Taiwanese Junk!LOL...
I figured maybe the heat is what was doing in my Autozone struts early. I did get some heat tubing wrap from Racing Sumit, which looks ok but I usually just slip them off at shows. Next time they fail I will put in the struts rod down, but so far with that heat wrap things seem to be ok.
