Got these installed today, "mann" are they nice! I only drove with them for about 45 minutes but I actually felt decompression in my back after. I'm not a big fan of aftermarket mods, especially really expensive ones, but I was getting to the point of not being able to use this truck anymore with my back problems.
For the install, I was never able to find off the shelf adapters to mount them to the suspension seat bases but Sire Custom Performance in Inglewood, CA did a great job fabricating them for me. I was worried they would be a little high but the seating position is perfect.
At some point I can provide photos of the adapters they made to anyone else who is trying to do the same thing. They are very rigid and compact.
