RE: All About Retracts - A Tutorial (Hopefully)
It is tough to match Spring Air. I have used them for years and will not switch to any other. They are easy to install as each gear only has one air line and they are dependable. I would recommend staying away from the 5/32 inch wire struts and go with the 3/16 inch strut units. They are designed to be in the down position and it takes air to hold them up. Robart has released a seris of gear that do the same thing, but I have not tried them so I cannot speak to how they work. Good Luck, Dave
