The 9454 54-Tooth Spur Gear (32-Pitch) is engineered for Traxxas 2WD models equipped with the Torque Control Slipper Clutch. This gear allows you to fine-tune your model's performance by adjusting gear ratios to optimize acceleration and top speed based on your running conditions. Swap ratios to balance raw speed against responsive acceleration for track, off-road, or casual driving. For detailed gearing recommendations specific to your model, consult your owner's manual to ensure proper fitment and performance.
