Traxxas 400 High Torque Metal Gear Waterproof Brushless Servo (Red) (High Voltage)
About this part
The Power to Perform
With over 3 times more torque than the standard #2075 servo, the High-Torque 400 provides noticeably faster turning speed and works great with TSM™ equipped vehicles. Traxxas High-Torque servos are the perfect upgrade for high-demand applications like Unlimited Desert Racer, Slash, Stampede, or almost any 1/10 Traxxas vehicle requiring extreme performance. Replace the E-Revo's dual servos with a single #2255 for lighter weight, more torque, and lightning-quick steering response. Elevate your steering performance to the next level with the High-Torque red 400 servo.
Waterproof Not "Water Resistant"
Traxxas knows the difference between “water resistant” and waterproof. Traxxas High-Torque servos are completely waterproof to give you the freedom to run when you want, where you want. Power through streams and bogs without fear while trucks with “water resistant” servos are stuck on the sidelines.
For TRX-4 Installation
The Traxxas High-Torque 400 Red servo represents a huge power upgrade for the TRX-4. When installing this servo, it is required that you use the High-Voltage BEC kit (TRA2262) and a steel servo horn (TRA8247X) is recommended. Installing the BEC is easy with plug and play simplicity. The kit includes a larger receiver box cover to maintain total waterproof integrity and a Y harness for vehicles with LED light kits.

You would think for 100$ you could expect a little quality but this "top rated" traxxas servo will disappoint you. Installed on my slash 4x4 vxl and ran it for about 1 week before i noticed my steering becoming unpredictable like, sometimes would turn as it should and other times wouldnt turn very hard at full steer. as if the servo saver was bad but it was brand new; it had to be the servo. at close inspection i realized the toothed shaft that you attach the horn to, is actually rocking back and forth inside the servo casing as i use the radio to turn the servo. i took the casing off and found RIDICULOUSNESS! There are 2 bearings on the shaft as advertised, but one is just sitting on the shaft loosly doing nothing, right next to/below the top bearing that rides in the lid of the casing. the bottom of the shaft is not fixed to anything, and there is/never was a slot for the 2nd bearing to seat into! so, no wonder this shaft is rocking back and forth when i use the servo. also, if you pay 100$ for a servo, it should be a FULL aluminum case. dont buy traxxas servos. dont buy savox either, their servos have no tolerance for moisture, they dont reply to rma requests or any tech support requests at all and their pricing is over 2x what it should be. instead buy a nice 100$ made in china with 400oz torque, .08ms timing, fully programmable, all aluminum housing and ipv6 waterproofing. imagine what traxxas and savox would charge for all those features.
In 6 months this servo has died. Traxxas wants half the price to fix it. I'm putting my money else where.
Pretty good servo, thought it was going to be more powerful for turning my 2.2s, but I'm not complaining about it. Has plenty of power and can turn those wheels in some tight spots, just thought it was be more. 4 stars because I installed a metal servo horn on it as well and it didn't quite line up perfectly, trim has to be off to the right a bit to get it straight, even after trying to re set the horn several times.
Do yourself a favor and pass on this purchase. This is straight false advertisement. It reaches no where near 400oz it doesn't even reach 300oz. The transit speed at 0.15 is alright but there are other servos with better speeds, torque and reliability out there.
1 week in a slash ultimate.... and servo is dead. I opened it up and the circuit board fried. Motor and gears are fine. Gotta find something else. For $100 there are many options.. 2 traxxas servos dead in under a month.
Reviewers are largely negative about this Traxxas 400 high-torque metal gear waterproof servo (red variant). The most common complaints are early failures, often within weeks or months, including a fried circuit board and a shaft that rocks inside the casing due to a loose bearing. Several reviewers also report torque below the advertised 400oz and centering or twitching problems. A few reviewers report good long-term use and strong torque, and one notes a horn alignment issue requiring trim adjustment. Reviews are split, with a clear majority citing reliability problems relative to the price.
- + Strong torque while working
- + Plenty of power for some reviewers
- + Long-term reliability for some owners
- − Early failures within weeks or months
- − Shaft rocks due to loose bearing
- − Torque below advertised 400oz
- − Erratic centering or twitching
