Thanks, that helps prove my point about 34 tons being a lie. A 5" ram with an area of 19.6 sq inches of surface area would require 3500 psi from the pump to generate 68,000 pounds of pressure (34 tons). The two largest mfgs of these pumps (Haldex and Dyn) are both advertised at a peak psi of 3000. At 3000 psi (the max capable of most all pumps of this style) this splitter will produce 58,800 pounds of force or a bit over 29 tons. Most mfgs set the relief settings of their valves at 2250 psi (not saying this one did, but most do) which would effectively produce 44,100 pounds of force, or 22 tons.
These guys are not the only ones that pull this marketing gimmick, but it just cheeses me off that any of them get away with it.

The other thing that I noticed about this splitter is that with a 5" ram, they are using a 13gpm pump. This thing is gonna be S-L-O-W.
