Traxxas Revo 2-Speed Standard Ratio Gear Set (2nd speed gear 39T, 13T-17T input gears

This is a replacement set of two speed standard ratio gear set for the Traxxas Revo. Only Revo offers the ability to custom tailor the 2-speed gear ratios for either wide or close ratio gear shifts. The close ratio set reduces the engine’s RPM change between first and second gear for nearly seamless shifting and speed, even in the corners! Choose wide ratio gear set to allow Revo to run in first gear longer through the infield, shifting later for a big run down the straightaway.
