Traxxas 12-T Pinion Gear 1.0 Metric Pitch 5mm Shaft RC TRX6485X

Overview

The Traxxas 12-T Pinion Gear (1.0 metric pitch) Set (fits 5mm shaft) TRX6485X is an essential upgrade and replacement component designed for high-performance RC monster trucks and extreme-duty applications. Whether you're maintaining your Traxxas X-Maxx, XRT, or other compatible brushless RC vehicles, this hardened steel pinion gear delivers the durability and precision engineering you'd expect from Traxxas, the world's leading manufacturer of ready to run RC cars and trucks. This is the perfect part for serious RC enthusiasts and competitive bashers who demand reliability and performance from every component in their drivetrain.

Featuring Module 1.0 metric pitch construction, this 12-tooth pinion gear represents a significant upgrade in tooth size and strength compared to standard 32-pitch gears found on many RC vehicles. The larger teeth mean greater load-carrying capacity, which translates directly to improved durability when launching hard, landing jumps, and hammering through rough terrain at speed. If you're running a brushless RC monster truck or high-powered RC vehicle in the UK, choosing the right pinion gear is crucial to maximising the lifespan of your drivetrain and maintaining consistent performance run after run.

This genuine Traxxas component is engineered to work seamlessly with steel spur gears and includes everything you need for installation, making it an ideal choice for maintenance, repairs, or performance tuning of your RC car or truck.

Key Features

• Module 1.0 Metric Pitch Construction — This is the metric equivalent of 25.4 pitch, which means significantly larger and stronger teeth compared to the standard 32-pitch gears used on many RC vehicles, allowing the pinion to handle extreme torque loads without stripping or breaking under the stresses of high-speed driving and aggressive terrain.
• 12-Tooth Configuration — The 12-T tooth count provides an ideal balance between acceleration and top speed for monster trucks and high-powered RC vehicles, making it suitable for both speed runs and technical driving where control and responsiveness matter.
• Hardened Steel Construction — Made from premium hardened steel, this pinion gear is engineered to resist wear, deformation, and damage during intense use, ensuring long-term durability even when paired with steel spur gears and subjected to the extreme forces generated by brushless motor systems running at thousands of RPM.
• 5mm Shaft Compatibility — The 5mm bore diameter fits perfectly with the motor shafts found on Traxxas X-Maxx, XRT, and other compatible high-performance RC monsters and trucks, ensuring a secure fit with no wobble or misalignment.
• Includes Set Screw — The gear comes complete with a set screw for simple, reliable installation and retention on your motor shaft, eliminating the need to source additional hardware and ensuring the pinion stays firmly in place during all driving conditions.
• Compatible with Steel Spur Gears — This pinion is specifically engineered to mesh perfectly with steel spur gears used in extreme-duty applications, making it the correct choice for your Traxxas X-Maxx, XRT Ultimate, and other brushless RC models that demand the strongest possible drivetrain components.
• Traxxas Genuine OEM Part — As an officially manufactured Traxxas component, this pinion gear meets the exact same specifications and quality standards as the parts installed on factory-fresh RTR models, giving you peace of mind that you're fitting genuine components to your RC vehicle.

Technical Performance

The Traxxas 12-T Pinion Gear represents the pinnacle of drivetrain engineering for extreme-duty RC applications. Module 1.0 metric pitch is a heavy-duty standard specifically engineered for high-torque, high-speed vehicles that demand exceptional strength from every rotating component. This tooth profile is approximately 25.4 pitch in imperial measurements, offering tooth dimensions that are significantly larger and more robust than conventional 32-pitch gears. The hardened steel construction resists the cyclical stresses of rapid acceleration, deceleration, and impact loading that occur when driving a brushless RC monster truck at speeds exceeding 50 mph over rough terrain. When paired with the steel spur gears found in Traxxas X-Maxx models equipped with Velineon brushless power systems, this pinion delivers reliable torque transmission and maintains engagement under the extreme loads generated by 1200XL or 540XL brushless motors operating at 35,000+ RPM. The 5mm shaft bore is machined to precise tolerances, ensuring a snug fit on motor shafts without play, which is essential for consistent gear meshing and efficient power delivery. The included set screw provides positive retention, preventing any possibility of the pinion slipping on the shaft during hard acceleration or deceleration. UK RC enthusiasts who demand the highest performance standards from their brushless RC cars and trucks will appreciate the engineering precision and material quality that Traxxas has invested in this component.

Frequently Asked Questions

• What vehicles is this pinion gear compatible with? — This 12-T pinion gear with 1.0 metric pitch and 5mm shaft is compatible with a range of high-performance Traxxas models including the X-Maxx Belted 4WD Brushless RTR (available in red, green, orange and blue), X-Maxx Ultimate variants, XRT VXL-8S (available in multiple colours), and XRT Ultimate models. If you own any of these brushless RC monster trucks or high-speed off-road vehicles, this pinion will fit perfectly.
• Why would I need to replace my pinion gear? — Pinion gears experience wear over time due to the constant meshing with the spur gear, especially when driving your RC monster truck at maximum throttle, landing jumps, and operating in rough terrain. If you notice grinding sounds, difficulty engaging the spur gear, or visible wear on the teeth, it's time to replace your pinion with this genuine Traxxas component to restore smooth power delivery and prevent damage to other drivetrain parts.
• Is this Module 1.0 pitch stronger than standard gears? — Yes, Module 1.0 metric pitch gears have significantly larger teeth compared to the 32-pitch standard found on many RC cars and trucks. The larger tooth profile means greater surface area for load distribution, reduced contact stress during power transfer, and improved resistance to breaking or stripping when subjected to the extreme torque loads generated by brushless motors in brushless RC vehicles. This is why Traxxas specifies Module 1.0 components for their monster trucks.
• Can I use this pinion with spur gears from other manufacturers? — This pinion is specifically engineered to work with steel spur gears in the Module 1.0 metric pitch standard. For optimal performance and to avoid damaging either the pinion or spur gear, you should use Traxxas genuine steel spur gears that are matched to this pinion's specification. Mixing gears from different manufacturers or pitch standards can result in poor meshing, excessive wear, and premature failure.
• Do I need any special tools to install this pinion? — Installation is straightforward and requires only a small hex key or screwdriver to tighten the included set screw. Make sure the motor shaft is clean and free of dirt before sliding the pinion on, then tighten the set screw securely to prevent slippage during driving. No special tools, presses, or technical expertise is required — this is a bolt-on replacement that any RC enthusiast can install in minutes.
• How often should I replace my pinion gear? — The lifespan of your pinion depends on driving frequency, terrain, driving style, and maintenance habits. If you're a regular basher running your brushless RC monster truck multiple times per week on rough ground at high speeds, you might replace your pinion every 6-12 months. Casual drivers or those running on smoother surfaces may find their pinions last much longer. Regular inspection during maintenance intervals will help you spot wear before it becomes a problem.
• What is Traxxas Cush Drive and how does it relate to this pinion? — Cush Drive is Traxxas's innovative shock-absorption system that uses an elastomer cushion between the spur gear and its hub to protect the drivetrain from sudden impacts and extreme loads. This 12-T pinion works in conjunction with Cush Drive spur gears to provide redundant shock protection, ensuring that your entire drivetrain is shielded from the punishing forces of jumps, hard launches, and rough terrain. Together, the pinion and Cush Drive spur gear create an extremely durable drivetrain suitable for the most demanding RC applications.
