This is an authentic Traxxas component, manufactured to the same exacting standards as the original equipment fitted to new models. The 5mm shaft bore ensures compatibility with Traxxas brushless RC vehicles in this scale category, and the Mod 1 (1.0 metric pitch) specification guarantees perfect meshing with the corresponding spur gear. For RC enthusiasts in the UK who value quality, durability, and genuine performance enhancements, this pinion gear represents an excellent investment in maintaining your prized RC collection.

Key Features

• 15-Tooth Configuration — The 15-tooth count provides an optimal balance between acceleration and top speed, delivering smooth power delivery through the drivetrain of your brushless RC vehicle without excessive strain on the motor or ESC.
• 1.0 Metric Pitch (Mod 1) — This precise pitch specification ensures perfect meshing with compatible steel spur gears, eliminating gaps that could cause drivetrain noise, vibration, or premature wear in high-performance RC buggies and trucks.
• 5mm Shaft Bore — The 5mm shaft diameter is the standard specification for Traxxas brushless RC vehicles in this category, guaranteeing secure fitment and reliable power transmission during aggressive driving and high-speed runs.
• Compatible with Steel Spur Gears — This pinion gear is engineered to work optimally with corresponding steel spur gears, providing durability and longevity that plastic alternatives cannot match in demanding RC applications.
• Traxxas Quality Manufacturing — As an official Traxxas component, this pinion gear meets the same rigorous quality standards as factory-fitted equipment, ensuring consistent performance and reliability whether you're racing or weekend bashing.

Compatibility Matrix

This pinion gear is specifically designed for compatibility with a comprehensive range of current-generation Traxxas models. It fits the entire Maxx Slash 1/8 4WD 6S brushless short course truck lineup, which is available in Red, Green, Rock N Roll, and Blue colours. The WideMaxx monster truck range in Red, Rock N Roll, and Green also accepts this pinion gear, as do the flagship X-Maxx Belted 4WD brushless 8S monster trucks in Orange, Blue, Red, and Green finishes. Additionally, the X-Maxx Ultimate variants in Blue X and Green X are compatible. Professional racers and serious hobbyists will appreciate that both the XRT VXL-8S models in Green, Black, Blue, and Orange, as well as the XRT Ultimate variants in Blue X and Green X, all utilise this exact pinion gear specification. This broad compatibility makes it an essential spare part for anyone running multiple Traxxas brushless RC vehicles.

Technical Performance

The Traxxas 15-T Pinion Gear represents precision engineering at its finest, manufactured from durable materials that withstand the extreme stresses of high-performance RC driving. At 1.0 metric pitch (Mod 1), this gear provides a perfect interface with Traxxas steel spur gears, ensuring smooth power transmission with minimal backlash and vibration. The 15-tooth configuration strikes an excellent balance for vehicles powered by brushless motors running 6S and 8S LiPo batteries, which can exceed speeds of 70+ mph in vehicles like the Maxx Slash. The 5mm shaft bore accommodates Traxxas standard motor shafts with precision fit, eliminating wobble whilst allowing for straightforward installation and removal. When paired with the correct steel spur gear, this pinion gear delivers optimal acceleration characteristics for short course trucks and monster trucks alike, whether you're competing in UK RC racing events or simply enjoying high-speed weekend bashing. The hardened material construction resists stripping and wear even under the demanding conditions of continuous high-speed running and hard acceleration, making this a reliable long-term investment for your RC collection.

Frequently Asked Questions

• Which Traxxas models does the 15-T pinion gear fit? — This pinion gear is compatible with the entire Maxx Slash short course truck range (Red, Green, Rock N Roll, Blue), WideMaxx monster trucks (Red, Rock N Roll, Green), X-Maxx Belted brushless 8S models (Orange, Blue, Red, Green and Ultimate variants), and XRT VXL-8S models (Green, Black, Blue, Orange and Ultimate variants). It fits any Traxxas model requiring a Mod 1 pitch pinion with 5mm shaft bore.
• What is the difference between a 15-tooth and other pinion gear tooth counts? — Pinion gear tooth count directly affects your RC vehicle's gearing. A 15-tooth pinion offers balanced acceleration and top speed for most driving conditions. Lower tooth counts (13-14T) provide more top speed but less acceleration, whilst higher counts (16-17T) offer quicker acceleration but lower top speed. The 15-T is considered a versatile mid-range option ideal for mixed driving.
• Can I use this pinion gear with plastic spur gears? — Whilst this pinion gear is engineered to work with steel spur gears, it may be compatible with quality plastic alternatives. However, Traxxas recommends pairing with steel spur gears for maximum durability and longevity, especially when running high-performance brushless motors on 6S and 8S LiPo batteries that deliver extreme power.
• How do I install the Traxxas 15-T pinion gear? — Installation requires basic RC maintenance skills. You'll need to access the motor shaft area of your vehicle, typically requiring removal of body panels and gear cover. The pinion gear slides onto the 5mm motor shaft and is usually secured with a set screw. A pinion gear puller tool is recommended for safe removal of old gears without damaging the shaft.
• What is Mod 1 metric pitch and why does it matter? — Mod 1 (1.0 metric pitch) is a precise gear specification that defines the size and spacing of gear teeth. Using the correct pitch (Mod 1) ensures perfect meshing between pinion and spur gear, eliminating gaps that cause noise, vibration, and accelerated wear. Mixing different pitches will cause drivetrain problems and potential damage.
• Will this pinion gear improve my RC vehicle's performance? — A replacement pinion gear won't significantly change performance unless your original gear is worn or damaged. However, upgrading to a different tooth count (if your model allows) can optimise acceleration or top speed for your driving style. This 15-T is the standard specification and represents the optimal balance for most Traxxas brushless models.
• Is this suitable for beginners? — Whilst this is an authentic Traxxas component, pinion gear replacement requires intermediate mechanical knowledge and proper tools. Beginners should have this service performed at a specialist RC workshop or by experienced enthusiasts. However, having spare pinion gears available is always recommended as wear is inevitable with high-performance driving.
• How often will I need to replace this pinion gear? — Pinion gear lifespan depends on driving style, surface conditions, and maintenance. With proper care and using matched steel spur gears, a quality Traxxas pinion should last 50+ hours of moderate to heavy use. Regular inspection and prompt replacement of worn gears prevents spur gear damage and extends overall drivetrain life.
