Yes, all the rest want you to remove the bumper & hitch. Then hinge the bumper with the bed. Mr. Hot Air sez 'cut 3 inches off the frame', OK, but then you gotta buy his special hitch that drags the ground when loaded. His main arguement against hydraulics is oil leaks and filling the reservoir. I had one of my first generation kits on a '78 Silverado that dumped on a daily basis from 1982 thru 1994. No leaks, no fills, and was working when I sold the truck for the same price I paid.
Ever have to drain water out of your air compressor? His air compressor is based on a goat milking machine (no shit). Personally I think that system is as pleasing to the eye as a hot poker. And no matter what he does, he'll never go to hydraulics, and never dump over the bumper.
In the history of mankind, no hydraulic scissor hoist has ever had 180 degree sweep until now. I can increase, or decrease the diameter of the cylinder to adjust the lifting capacity. I can lock the scissor in the open position with a safety pin, and swap the cylinder out with two snap rings and two hoses. The cylinder has a three year warranty, and replacement cost is about $150. Wonder how much an airbag costs.
All the pins are 304 stainless steel, this early version doesn't show the grease fittings at every pivot. Not that it needs grease, but some of my customers have this crazy idea that the pivots must be spinning at 3000 RPM all day. They really go 90 degrees and stop a few times a day at best. Anyway, you want to grease it, no problem!
