About this part

This is an extra strong plastic servo saver from Kimbrough, designed to work with all brands of servos. This servo saver comes with a small tree with three different splines on it for adapting the servo saver to work with KO, Airtronics, JR, Futaba, Thunder Tiger and Hitec servos. Kimbrough makes some of the best servo horns in the business, and their servo savers are second to none! If you have a high stress application where you do not have an existing servo save, you can use this servo saver to help save the gear of the servo during hard crashes. Great for steering applications on big monster trucks!

love it, used on my smt10 with 2.6 firestorms and works great.

We upgraded the servo in the Arrma Granite which had 25T so the stock servo saver wouldnt work. This universal servo saver worked great with little trimming. I Would recommend this for a replacement.

Not quite sure how to rate this, on one hand it did it's job. On the other hand it broke first time out, so..... I'll order another and see if it survives a bit longer. Installed on a LOSI LMT

Too soft for my Pro-Mod Axial SMT-10 based 1/10 monster.

These have been my go too for years! They are perfect for 1/10 trucks and I use them on my Traxxas Stampede's. I've never stripped servo gears with this installed, and the spring is strong enough to turn the big 2.8 tires on the trucks!

What reviewers say

Reviewers generally report that the Kimbrough Large Extra Strong Servo Saver (Universal Spline Connector) performs its protective role on 1/10 trucks, including Traxxas Stampede, Arrma Granite, Losi LMT, and Axial SMT-10 builds, with some praising its spring strength and that it protects servo gears. Experiences vary: one reviewer reports it broke on first use, another reports the plastic shattering at the horn adapter within minutes, and one finds it too soft for a high-powered Pro-Mod SMT-10 setup. Fitting sometimes required trimming or boring holes, and one reviewer noted a 25T horn needed modification to fit. Several reviews are older, and the sample is small, so durability appears inconsistent.

  • + Strong spring
  • + Works with universal spline fit
  • + Good replacement option
