New for the HPI Baja are these innovative Helical Gear Sets from Area RC! These gear sets feature a hardened steel outer ring with a T6 aluminum inner mount. But what makes them so unique is their helical cut teeth which makes for a smoother, quieter gear mesh compared to standard straight cut gears. They are available in four variations including 51/20, 52/19, 53/18, and 54/17 gear ratios for all track conditions.
