This is an optional 45 tooth Robinson Racing Slash/Stampede 4×4 32P Hardened Steel Spur Gear. This precision machined, hardened steel spur features a blackened finish that improves lubricity (the capacity to reduce friction) and anti-galling (metal cracking/breaking from friction) characteristics resulting in better mating surfaces and smoother running gears.
NOTE: Does not accept telemetry.
