Gear set, 2-speed standard ratio (2nd speed gear 39T, 13T-17T input gears, hardware)
 
Only Revo & Slayer offer the ability to custom tailor the 2-speed gear ratios for either close or standard ratio gear shifts (wide ratio is stock). 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!
