That has nothing to do with it at all. You just have to size a DE cylinder differently than a SE cylinder because you have to account for the shaft being inside of a DE cylinder. The only advantage to a SE cylinder is mounting space. DE will be "balanced" left to right so it won't have more force when extending one way, and act quicker(but with less force) the opposite.
Read Billavista's article.

Surplus does have dual ENDED rams though(which I guess is what you were trying to get at?)... but I was saying to go with PSC or similar for street driving not because of that, but because the cheap rams have CLEVISES vs heim joints.
But there are ways around that too, check out what this guy did to a cheap ram to make it accept heim joints... scroll down to post #370:
