Steering Servo Upgrade Guide
Find Out Which Servo Is Right for You
Traxxas models come equipped with durable, powerful, high-quality steering servos from the factory. Each servo is chosen to match the performance of its model and ensure exciting RC fun right out of the box. For the ultimate in steering precision and an ultra-responsive feel at the wheel, Traxxas offers extreme-performance upgrade servos. An upgraded servo can enhance your driving experience further with boosted steering torque, faster action, and even greater durability. Let’s take a look at the Traxxas servo lineup and which is right for your model.
Torque Talk
The higher a servo’s torque rating, the more power it has to push and pull the steering system’s linkages. That extra power is especially welcome for larger, heavier models and their larger, heavier tires. The extra heft and the torque required to muscle it around also puts a greater load on the servo gears. This is why Traxxas upgrade servos have metal gears. Servo torque is measured in ounce-inches and indicates the force that the servo can apply via a one-inch lever. If you find that hard to visualize, no worries—all you need to know is the higher the torque number, the more powerful the servo.

2065R Sub-Micro Metal Gear Servo
If you’re wheeling a TRX-4m™, your truck includes a 2065T servo with a metal main gear for superior durability to an all-composite gearset. For the ultimate in trail-proof strength, the 2065R servo features a complete set of metal gears. If you’re hitting comp-style courses and outfitted your rig with heavyweight brass accessories or larger wheels and tires, a 2065R is an excellent durability upgrade.
2080R Micro Metal Gear Servo
The 2080R is a perfect upgrade when your 1/16 Slash®, E-Revo®, or Summit® is ready for a new servo. You get the same responsive steering as the standard composite-gear servo provides, but with a full set of metal gears for enhanced durability. You can also upgrade your full-size TRX-4's shift servos with the metal-gear upgrade. It's unlikely that you would need to upgrade, but a little overkill never hurts.
Standard Size Servos
2075X and 2075R Standard Size Metal Gear Servos
The 2075R and 2075X metal-gear servos differ only in their gear ratios. The 2075R is geared for speed, 2075X is geared for maximum torque. Either servo makes a nice upgrade for your your Bandit®, Revo®, Rustler®, Stampede®, or Slash® with a metal-gear durability boost.
2270 High Torque Metal Gear Servo
This servo’s a sleeper–it looks just like the 2075X/R units and has the same standard 1/10 scale dimensions, but it’s packing a mighty 236 oz-in of tire-twisting torque. That’s a massive 88% boost in steering power compared to the 2075X/R. This makes it a great upgrade for TRX-4® and TRX-6® trucks or any big-tire machine. In fact, the 2270 is standard equipment for the TRX-4 with Traxx. Swinging those beefy tracks demands a lot of servo muscle, and the 2270 delivers.
All Traxxas metal-gear servos are fully waterproof, not merely water resistant, so there’s no stopping for rain, mud, or snow. There’s no limit to RC adventure with Traxxas waterproof electronics.
2250 High Torque 330 Metal Gear Servo
Now we’re getting into the really heavy hitters. The High-Torque 330 yanks the steering links with 330 oz-in of torque (hence the name), and that blue-anodized mid-case adds more than just style. The aluminum case sheds heat to keep the servo motor cool, ensuring peak performance from start to finish during extended crawls and all-day speed sessions. Also unique to the 330: coreless motor construction, which provides lightning-quick response and superior command precision compared to standard wound-armature servo motors.
2275 High Torque 347 Metal Gear Servo
The 2275 has an aluminum mid-case and 347 oz-in of torque! This servo belongs to Sledge, Traxxas’ 70+ mph, 12.8 pound (14+ pounds with batteries on board), extreme-performance 1/8 scale truck. The High-Torque 347 steers this hefty, hard-hitting machine with authority yet still fits within a standard-servo footprint, allowing the 347 to also be used as an upgrade servo for most Traxxas models equipped with 2056- or 2075-series servos.
Up to this point, all the upgraded servos we've looked at were designed to run off standard BEC power from your model's electronic speed control. These next two servors are so powerful, that you'll need to upgrade your TRX-4 and TRX-6 to the High-Power BEC Kit. This standalone BEC is perfect for TRX-4 with more than enough power for even the largest servos and heaviest trucks.
Brushless Standard Size Servos
2255 Brushless High Torque 400 Metal Gear Servo
This powerhouse is packed with high-performance features including a full-metal gearset, anodized aluminum midcase, and a brushless motor. The benefits of going brushless with a servo motor are the same as going brushless to power your car or truck: you get more torque, higher RPM, and greater efficiency. 400 oz-in of torque works out to 25 pounds of force, more than enough for even the largest Traxxas models. The High Torque 400 is perfect for TRX-4 and TRX-6 trucks, where maximum servo muscle is required to push and pull large-diameter wheels wearing super-soft, ultra-sticky tires under heavily weighted trucks moving at a crawl pace–or even stationary. For that type of extra-extreme duty, nothing tops the 400 Red.
2280 Brushless High Torque 600 Metal Gear Servo
This is the new top dog in the Traxxas servo lineup. Like the 2255, the 2280 uses brushless motor technology to pump out its 600 oz-in of torque at 6 volts. It you step up to 7.4 volts, this amazing powerhouse puts out over 700 oz-in of torque. That's nearly five times the power of a standard 2075 servo! The High Torque 600 features a full aluminum case with cooling fins for extra heat dissipation. Despite its massive power output, the 2280 still fits most Traxxas vehicles that take a standard size servo. Just be sensible with all that power!
Large Scale Servos
More Metal = More Strength
Even though brushless standard-size servos have more than enough torque for even the largest Traxxas vehicles, there's simpy no substitute for more metal. These Maxx-sized servos pack larger metal gears for maximum durability when you're pushing around 8-inch tires on a 20-pound truck. Give your Maxx®, X-Maxx®, or XRT® the ultimate steering upgrade with one of these monster servos.

2085X Maxx-Duty® Servo
When it comes to turning Maxx-size wheels, you need a Maxx-Duty servo. The 2085X Maxx-Duty servo puts out a stump-pulling 450 oz-in of torque at 6 volts with an all-metal gear driveline and finned aluminum mid-case. It even comes with a super-stiff servo saver spring to prevent the bellcranks from "camming out" too easily when you're cranking the wheel.
2085R High-Torque Maxx-Duty Servo
The 2085X is good enough for almost any X-Truck™ driver, but for those X-Maxx and XRT owners who wake up in "full send" mode, the 2085R packs a phenomenal punch. Like the 2085X, the 2085R features a full steel drivetrain, finned aluminum case, and larger servo saver spring. Where they differ is the 2085R's staggering 650 oz-in of torque at 6 volts! When nothing but the best will do, it's time to upgrade your X-Truck to the 2085R High-Torque Maxx-Duty Servo.
