Driveshaft's, rear, steel-spline constant-velocity (complete assembly) (2) (fits 2WD Rustler/Stampede) Traxxas Steel Constant Velocity Shafts offer the ultimate in torque handling and efficient power transfer. The outer U-joints are lubricated and sealed by a rubber boot for maximum protection against the elements, and the U-joint pins are held captive so you never have to worry about losing a pin.
