What kinda shock is this??

[lwb66]

I was looking at starting the suspension work on my 66 and noticed the front shocks and i have never seen one of these before. I also found that the whole frame had been painted and all new body mounts were installed..Thats a bonus for sure.. See i inherited this truck a month ago so i'm still going over everything and seeing what all was already done or needs to be replaced. But the shocks I have never seen before.. Looks like they are only a couple of years old and still work good. Just curious is anyone else has them and knows what they are called and possibly who makes them ..
