The MST NS High-Torque Servo Saver is a great option for a variety of applications. The multi piece design includes 23T and 25T splined outputs, and is combined with the short 16.5mm length horn, or the long 17.5/21.5mm length dual hole horn, and either the red (soft), gold (medium) or silver (hard) spring to adjust the servo saver tension.

MST NS High-Torque Servo Saver
Been using one for ~6 months in a wheeler. Works well, inexpensive, well built, and adjustable. The 3 springs do provide different tensions. Also comes with 25 and 23 spline mounts. With the strongest spring the tension is very high but it will give a little without giving up much if any slop.

Over time mine exhibited wear and started binding. A light sanding can rejuvenate it but it will probably occur again sooner. But this is a nice servo saver and works well and I will replace them.
