Traxxas Two Speed Conversion Kit E-Maxx RC Gearbox & Drivetrain Part - 3998

The Traxxas TRX3998 Two Speed Conversion Kit is a drivetrain upgrade designed specifically for the Traxxas E-Maxx, adding a two-speed transmission system to models that run a single-speed setup. The kit includes both wide and close ratio gear options, giving E-Maxx owners the ability to tailor gearing to their driving style — whether that's low-end torque for crawling and bashing or higher top speed on open ground. If you're looking to get more versatility out of your E-Maxx's drivetrain, this conversion kit is the direct-fit solution from Traxxas.
