Review: Super strong! - The only brand i buy my pinions from now. Not even a chip in the teeth when it slides off while rippin around. A+
Review: Quality and lager grub screw - Bought this because my xmaxx pinion has a tendency to loosen. This was suggested as it has a larger grub screw. Only complaint is that it is narrow.
