Losi Pinion Gear 17T Mini JRX2

Keep your Losi Mini JRX2 buggy geared correctly with this genuine Losi Pinion Gear, featuring a 17-tooth count, a 0.5 Mod pitch, and a 2mm shaft bore built specifically for this compact 1/16-scale platform. Because the Mini JRX2 uses a small, purpose-built drivetrain, using a pinion gear engineered and sized specifically for it is important for correct mesh, quiet operation, and long-term durability — generic or mismatched pinions can wear prematurely or slip under load. This 17-tooth option is a common choice for balancing snappy acceleration with usable top speed on typical off-road surfaces, making it a great gear to keep on hand for tuning performance to changing track conditions, battery types, or driving style. Manufactured by Losi to the same tolerances as the gearing that ships with the vehicle, this pinion drops in as a direct fit with no modification needed, seating securely on the 2mm motor shaft for a clean, quiet mesh with the stock spur gear. Whether you are replacing a worn or stripped pinion or simply experimenting with gear ratio to fine-tune your Mini JRX2's handling, this genuine Losi part is a simple, reliable upgrade for consistent drivetrain performance.
