Traxxas 12 tooth 32 pitch pinion gear is made of machined steel. Designed for a 3mm shaft.
INCLUDES: One 12 tooth Pinion Gear
One 3 x 4mm Set Screw
COMMENTS: This gear is only one of two which are used on the E-Maxx dual motor set-up.
Assembly onto an E-Maxx truck.
1.5mm hex wrench to tighten set screw.
The Gear seems to be cut smoothly and the set screw threaded easily. Glad I purchased this and price over local hobby shop is worth it, Thanks!
