The new box is smaller and less expensive to help capture more market share. The ratio is a tad faster at 14:1. You can't compare turns lock to lock, as they are the same. All this means is the new box turns a little more. The most important benefit is feel. These boxes are based on different type valving creating a much sharper on center feel. Fast ratio arms can be used with these too. The same rules apply with pressure, the more pressure, the lighter the effort. I sell a Saginaw pump that is set for 900 lbs which gives a nice feel and will still works in hydroboost applications too. The boxes are also covered by a 3 year warranty.
