About the Brand
Better than Traxxas
I'm all about OEM parts, so when I upgraded from a 13 tooth to a 16 tooth pinion gear on my Traxxas Sledge, I went with the Traxxas one. It broke after just one run, though it might've been bc a rock got jammed in there. This gear is much stronger, plus the worm screw is a size larger. When you get it, make sure to clean any oil off and use blue loctite on the motor shaft and screw. Let it sit for a day before hitting the tracks.
