Title says it all. Not "3d printed parts" or "xyz sensor", but a piece of hardware. What would you legalize, and why?

Steel springs. I say it with some hesitation, however. I know that, in the wrong hands, steel springs can be somewhat dangerous: the kind of thing that can put your eye out, kid. But so can a screw or chunk of C-channel that gets propelled by a highly stretched rubber band. In the hands of a careless person, anything can become dangerous.
To reduce the danger, they could sell such springs with their ends fully looped and perhaps some kind of rubber boot required (for compression springs). The springs would come in assorted sizes and the kids would not be allowed to cut them.
Reason for springs: I think they can be useful in making compact shock absorbers and for things like idler gears, compact gadgets of all sorts.
Another thing might be small metal cable with small pulleys, the kind of thing that could allow long-distance mechanical actuation of grippers, for example.

1) A motor coupler that goes right to a high strength shaft. The 12 tooth part is nice but the motor still only has the low strength, relatively easily twisted option. There was a motor gear designed in one of the previous online challenges that accomplished this. Seemed like a great idea to me.
2) Bearings. Not journal bearings like we have, but ball bearings. That may be out of the price range of Vex to make a nice housing with a high strength shaft in the center.
3) I know it's not mechanical, but current sensors to help you code to manage PTC trips. (yes the SmartMotor library helps you manage this already) More powerful motors is option 2, but you will always get to the new, more powerful PTC trip point.

Stepper Motors - They are widely used in the robotics / manufacturing industry and they are fun to use.

A new vex servo would be nice, one that uses a 393 size motor.

What would you use a servo for? A claw?
-
Metal bars with holes that can utilize high-strength shafts.
-
Definitely ball bearings.
Slip rings are cool but they aren't really necessary in general and an application you would use one for can usually be worked around without one. Plus I don't see VEX allowing mercury any time soon and the brush versions available commercially are very large.

@Liam Matthews Metal bars with holes that can utilize high-strength shafts.
Do you mean High Strength lock bars like these: http://www.technology-education-resources.com/media/d28e7d12b0a2c4d3ffff800fffffe417.pdf

no, like metal with holes the size of high strength bars
