Exactly as described. Using in a crawler so cannot day for speed running.

Worked like it said it would

These are really big and long. If you compare them to Robinson Racing's 32p pinions you'll see what I mean. I tried to use these with an old RC10 that I run 32p gears on. They were too long for the set screw to grab onto the motor shaft. I would avoid these.

Good value pack this, no complaints.
