This is a Tekno RC Lightened M6 Driveshaft Outdrive Cup Set and is intended for use with the Traxxas Slash, Slash 4x4 and Stampede 4x4 trucks equipped with optional Tekno RC M6 (6mm) Driveshafts. These Drive cups are CNC machined from steel, lightened, then hardened for durability. These are for the front or rear end  and use the stock M3 screw pin for installation.

Note: These are not compatible with the stock Traxxas drivetrain components, and must be used with Tekno M6 rear driveshafts (TKR6852X).
