Color: Black
Solid upgrade part. Installed easily and improved performance as expected.

  • Best servo for the price!
Color: Black
Strong and fast! At an ok price as well. Comparable to the reefs 99 but at a better price. So far unbreakable. (I have done all the things that have broken others) It is slightly longer than stock, but the wires come out of the side, so it can work to replace the stock servo (on trx4m) . I would take a star off because amazon had delivery problems, but I dont want that to reflect on Injora. Nothing but good products from them. ... show more

  • Great upgrade at a good price.
Color: Red
Servo looks great, black with aluminum cuts. Fit perfectly with the Injora aluminum axles. Much better performance than stock servo in speed, power, and durability, and price. This set comes with the servo, mount, and servo arm, for the price of the OEM servo alone. Semi easy to install (there are no instructions) If you are using the Injora aluminum axels you will need the 2 micro grub screws and a .05 allen key to install, but set servo into the mount first then tighten the grub screws, but not too tight. Not sure how it fit stock plastic axels. ... show more

  • Love it (Make sure you center your servos for your setup)
Color: Black
Love it. Mine came pre-centered ,I knew after I powered it up it was gonna be great . Its adds great weight to the front and is much quieter than the stock(my stock one destroyed its plastic gears). It installs just like the stock as well. Amazing price👍

  • Ok but needs improvement .
Color: Black
Works well with larger tires and weighted wheels. The servo isn’t designed for the TRX4m necessarily because 1 it’s a little tall. 2 the wiring comes out the front when it should come out the rear. The wiring blocks the screw and caused a cross threaded screw since the wiring is completely in the way. A ball hex will be required to access easily. It’s had an issue with the servo horn screw to the steering link keeps backing out even with threadlock and the thread isn’t stripped. If you work the steering back and forth it will loosen but if you tighten all the way it seems to bind the steering up so something seems to be designed wrong. I didn’t have this issue on my old stock servo even when I had aftermarket brass steering link on that one. ... show more
