Installed this into an SCX 10.3. I have yet to test it on a rock trail but so far it has been reliable.

This was exactly the right size and so far it is holding up great. I'm not the best driver and I keep hitting stuff that destroyed the stock servo in short order. This one has been going strong now for a full 2 months, it is not the weak link in the steering gear now.

Brought to replace the steering servo on my Traxxas Defender it fitted very easy and the cable was plenty long enough to reach receiver, I have now brought a spare for the future as I intend taking my Trx-4 on holiday to use.

No problem at all moving tires in all situations so far. Since installation, only time I've had time to drive is in the rain. So 4 hrs of water and mud with zero problems . Metal arm is nice so that's one less thing to worry about. Will definiely be buying more as I upgrade my other builds

Servo and arm fits perfect into Traxxas TRX4 rock crawler. Look up in the forums on how to switch servo direction if needed. Plenty strong enough for my stock TRX4.
