Can you really install the Gooseneck Surge in a couple of minutes? Yes check out the install video.
How much air do I put in the gooseneck surge air hitch? See air pressure video in install tab.
What do your mean when you say straight or angled / slotted pin holes? We are wondering if your gooseneck stem has holes that are straight across OR if it is slightly angled 10-30 degrees, where the stem hitch pin is off set or at an angle. Below is a picture of an angled stem, which we would use a stem with slotted holes to fit this angled pin. See our gooseneck stem selection guide.
Will it work with my flat bed pickup with recessed in a flatbed pocket? Yes, see install tab and fitment guide for recessed ball.

How does the air ride work? The air shocker is like a teeter totter. One end is an air bag, a pivot in the middle, and a ball at the other end. This gives a “pillow” effect at the ball end.
