This is an optional Traxxas Two Speed Conversion Kit, and is intended for use with the Traxxas E-Revo. In stock trim, the E-Revo (#5605) is equipped with a Brushless Ready single speed transmission that is optimized for all-around running. The optional Two-Speed Conversion Kit offers another dimension of versatility and performance for E-Revo owners who want the option of stump-pulling torque and high-speed passes. The included waterproof sub-micro servo actuates the internal shift fork with the push of a button from a three channel transmitter (sold separately).

The first ratio gear sets allow custom tuning for various applications and performance preferences. The close ratio first gear set is ideal for running through grass, mud bogging, and hill climbing; while the wide ratio first gear set delivers an amazing 50:1 final drive ratio for climbing serious terrain. This package includes wide and close ratio first gear sets, a sub-micro servo, and linkage.

NOTE: Requires 3 channel transmitter.
