Samix Aluminum Servo Horn for Traxxas TRX-4 (Black) (25T)
Super nice design with the double clamping screws. Excellent quality and fits my Protek Black series 370TBL crawler servo perfectly. Even with 650 oz-in of torque it has no problems...

#UPDATE# After using 4 different servos over the last year in my TRX4, all with this same Samix horn, the Protek 370TBL is the only servo that wasnt touching the servo horn when steering at least one direction. The current Savox SA-1283SG aluminum case servo had such littke clearance that it ended up binding and stripping the splines on the servo horn. Seems like it just sits about 1mm too low...

Samix Aluminum Servo Horn for Traxxas TRX-4 (Black) (25T)
Does not work well with the Savox 1283SG
horn touches the servo case and the chassis/brace at full lock
Center is also off half a spline
