You possibly have a couple things going on.
The knuckle stops do a couple things
1) They keep your inner tire from touching or binding on the leaf springs
2) They keep your Birfield joints from binding and breaking
There are also internal steering stops inside the Saginaw Steering Gear. Contrary to belief, (and another Steering Shop likes to add value to his products by claiming he builds his steering gears with internal stops) MOST ALL Saginaw Steering Gears have internal stops so don't be fooled if you experience that!
The internal steering stops are used to keep inner tire rub from happening as well on stock applications. For example, a steering gear is on a 6cyl Camaro with a skinny tire it has more room to rotate the wheel and tire, but the same year Camaro that is a SS or Z28 has a much wider wheel and tire and could be equipped with an internal steering stop to keep the tire rub from happening. Almost all makes and models of GM vehicles had steering stops in some and not others depending on that vehicle's trim package.
Is there a way to tell if your steering gear has in internal steering stop? Nope, not without taking it apart. There is one behind the piston and one in front of the piston. These steering stops are 50 thousands, 100 thousands and 200 thousands of an inch thick. And yes, that makes a difference in the steering gears final rotational reach (travel)
As far as a longer or shorter pitman arm, it also will change the drag link travel, not just speed the travel up or slow it down. I have universal heavy duty pitman arms that are not drilled for custom applications specifically for travel requirements, but they are all flat and typically used in desert racing and prerunner applications where the steering and suspension geometry are designed for a flat pitman arm.
It is possibly @RWBeringer4x4 that the steering gear has internal stops and could gain you some more steering angle with your current set up
