Senton Servo upgrade

[Fenwick17]

Looking for advice on servo replacement. Does tooth count matter if new servo has new arm? Would appreciate any advice and suggestions on brand, kg, etc. I already ordered hot racing servo saver. Thanks

Most are 25 tooth spline. As long at the Servo horn is 25 you’ll be okay. Jx eco boost and ecopower are both good servos

New servos don’t usually come with a servo saver, though, just the steering horn. If you’re racing on even terrain, the horn will probably be fine, but if you drive more on random rougher terrains, you will probably want to get a matching saver. The saver is a spring loaded horn that absorbs the hits of the tires being forced left/right from hitting the ground. Without the saver, those impacts go straight to the gearing in your new servo and will wear it out.
I just saw the end of your post. The HR servo saver will come with 3 plastic adaptors to fit your servo, so you’re good to go with that.
