From Exotek Racing:
In development since 2016 we are now ready to release our ultra lightweight premium machined pinion gears for 17.5 class racing!
Machined from black pom (delrin), for that stealthy look, our gears offer extra quiet operation with full face teeth (4.5mm) for excellent mesh and durability.
Also incorporates a machined alloy keyed collar for secure mounting with the included heavy duty 3mm set screw that uses standard 1.5mm hex wrenches.
The alloy collar is polished, anodized in black and has the teeth size clearly laser engraved.
For spec 17.5 class racing only.
