They are Gazi's. The guys in Brisbane built these especially. I wanted the ones that had the piggyback reservoirs but the wouldn't fit to the top shock mounts, so I then tried the lower rated ones. They are meant to be mounted with the bodies above and the shaft below but this also wouldn't clear the top mount without welding wider shock mount shafts or having the shocks wider at the bottom and their travel wouldn't be straight up and down, so the boys inverted the shocks and found they fitted perfectly.
This meant changing the valving so that they could be mounted in this way which also meant having separate chambers for nitrogen and oil...just like on their top of the range piggyback shocks. So I ended up getting the workings of the piggyback version in the basic body.
Absolutely great job and i couldn't be happier with them. I'm never quite sure of how much I spent but I think it was about $800 which was a real bargain Can't recommend the Brisbane Gazi guys enough. I'm ashamed to admit I can't remember their names, sorry.
