TRA3955 Spur gear, 40-tooth (1.0 metric pitch)
This is the optional 40 tooth spur gear for the Traxxas Revo monster truck. This spur gear goes on the gear box to transfer power from the clutch bell on the engine into the transmission case. The stock spur gear is a 38 tooth gear, so this 40 tooth gear will provide more bottom end acceleration with less top end speed than the stock gear.
This is a replacement 40T spur gear for the Traxxas Revo. This gear meshes with the clutch bell.
Features: Black plastic construction
Includes: One 1.0 metric pitch 40T spur gear
Requires: Nothing, this is a direct replacement part
