INJORA INJS2065 7KG Waterproof Servo with Mount and Horn for TRX4M

Fixes that “slop” that comes from the stock steering servo on the Traxxas TRX4M and makes crawling easier and more predictable! Easy enough on the install and includes the servo horn and stainless install screws! Would definitely recommend as one of the first upgrades since these factory ones usually give out fairly quick. Makes turning faster, stronger, and adds some much needed weight up front!

Perfect fit for trx4m and super easy to install. Servo is super strong and is pretty quiet for a relatively inexpensive servo option. Servo mount that’s available adds strength and feels like some good weight on the axle. Totally recommend. Will Be getting more for my other builds!

If you have a TRX4m you will need this sooner or later, especially once you start adding wheel and suspension weight. Once your stock servo gives up the ghost, this make for a super easy swap. I was able to simply unbolt the upper suspension links at the axle side, and roll the whole axle away from the body to gain sufficient access to swap the servo and mount. I also looked at some stronger servos, but the Injora 11KG wasn't waterproof, which was a dealbreaker, and the 15KG seemed like massive overkill. Plus those both required adding BECs. I'm glad I only went with the waterproof 7kg servo in the end. I used this on my F150 High Trail with 64mm tires, brass wheels, links, diffs, and hexes, and a +11mm total track width vs stock, and it works great. Plenty of power to push the truck out of tight spots, I haven't had it bind up yet. Also very quick to go from lock to lock. It's been submerged in water and didn't blink. It even looks great, I didn't realize the blue was metallic until I opened the box. From what I read the stock servo is 2.3-2.5KG, so this one is nearly 3x stronger. If your build is going to get super heavy with wide metal axles or lots of extra width, you might need something beefier, but this seems more than sufficient for most trail and light crawler builds and it's priced pretty nicely. Don't overthink it!

Ive bought countless parts for our 10scx and 18scx crawlers. Every single part ive bought has been top notch and atleast 2 times better than the name brand ones. Its always has spare parts and stickers which is a huge plus in my opinion. My only knock is i wish they had help videos as ive had to rely on my own research which is fine. I definitely recommend to all my buddies and family to Injora. Always durable, size is perfect, easy to install and always works.

It’s a decent servo, not incredibly strong though. It’s better than the stock servo.

Bought this for our 14-year-old son, for his Traxxas TRX4M. He said it was very easy to install and felt high quality. It's lasted him almost a year now, so very durable product. It fight the TRX4M perfectly.

Does not hold up if you have any power upgrades on your account. I burned through 3 of these in 1 day, and I was very careful to install correctly.

Strong quality and affordable

Amazing, strong servo . Needed if you are using the stock trx-4m servo if you are adding weight onto the car. Works amazing

Fit my bronco trx4m perfectly

Works perfectly

Nice

Funziona perfettamente, dopo aver cambiato due servosterzi originali, ho deciso di provare questo che sembra più robusto. Per ora funziona molto bene, vedremo se durerà nel tempo
