Traxxas Steel Spur Gear 50-Tooth Wide-Face 1.0 Metric Pitch TRX6448R

Overview

The Traxxas Spur 50-tooth, Steel (wide-face, 1.0 metric pitch) TRX6448R is a premium drivetrain component designed for serious RC enthusiasts looking to optimise the performance of their high-powered Traxxas models. Whether you're running a brushless RC monster truck, short-course truck, or sand car, this machined-steel spur gear represents the pinnacle of durability and power handling in the RC hobby. Built from solid steel and engineered with extra-wide teeth, this spur gear is an essential upgrade for anyone seeking maximum reliability during high-speed running or competitive use.

Traxxas spur gears are recognised across the UK RC community as the gold standard for performance upgrades. These drivetrain components allow you to fine-tune your RC car's characteristics by adjusting gear ratios, helping you strike the perfect balance between acceleration and top speed for your specific running conditions. Whether you're racing on the track, bashing in the garden, or tackling challenging terrain, the right spur gear makes all the difference to your RC experience. The 50-tooth configuration offers a particular sweet spot for many popular high-performance Traxxas models, making it one of the most sought-after gearing options for UK RC enthusiasts.

This is not a complete vehicle—it's a precision replacement part and performance upgrade component for compatible Traxxas models. If you're already running one of the supported Traxxas vehicles, this spur gear swap will unlock new performance potential without requiring a complete rebuild.

Key Features

• Machined-Steel Construction — The spur gear is machined from solid steel rather than cast or moulded, ensuring superior strength, precision and longevity compared to lower-quality alternatives, which translates to a longer service life even under extreme driving conditions.
• Extra-Wide Steel Teeth — The wide-face tooth profile distributes power load more evenly across the gear mesh, dramatically improving power handling capability and reducing the risk of tooth stripping or gear failure during aggressive acceleration or high-torque situations.
• 1.0 Metric Pitch — This standard pitch specification ensures compatibility with a wide range of Traxxas pinion gears and drivetrain components, allowing seamless integration into your existing setup without requiring additional modifications.
• 50-Tooth Configuration — The 50-tooth count provides an excellent balance for high-performance Traxxas models, offering competitive acceleration characteristics whilst maintaining reasonable top-speed capability across varying terrain and driving styles.
• Performance Tuning Capability — By changing spur gear ratios, you can optimise your RC car's performance for different conditions—larger tooth counts favour acceleration whilst smaller counts favour top speed, giving you complete control over your vehicle's characteristics.
• Genuine Traxxas Component — This is an authentic Traxxas factory part (Part Number TRX6448R), guaranteeing OEM quality, proper engineering tolerances, and full compatibility with your Traxxas model without any guesswork or fitment issues.

Technical Performance

The Traxxas Spur 50-tooth, Steel (wide-face, 1.0 metric pitch) TRX6448R represents the pinnacle of spur gear engineering for high-performance RC vehicles. Machined from solid steel rather than cast alternatives, this component offers superior rigidity and dimensional accuracy. The wide-face tooth design is critical for modern brushless RC cars, which deliver enormous torque and acceleration forces that would easily destroy standard gears. The 1.0 metric pitch specification aligns with Traxxas' entire drivetrain ecosystem, meaning you can confidently mix and match this spur gear with any compatible pinion gear without modification. The 50-tooth count positions this gear as a mid-range option within the Traxxas lineup—suitable for models where balanced performance is desired rather than extreme top-speed or maximum acceleration. Traxxas engineers specify which spur gear tooth count works best with each vehicle model, so consulting your owner's manual will ensure you're selecting the optimal ratio for your specific model. The steel construction combined with the wide-face profile means this gear can handle the full output of modern 6S and 8S brushless systems found in high-end Traxxas trucks and buggies without degradation.

Frequently Asked Questions

• Which Traxxas models is the 50-tooth steel spur gear compatible with? — This TRX6448R spur gear is designed for numerous high-performance Traxxas models, including the Maxx Slash 1/8 4WD 6S Brushless Short-Course Truck (in all colour options), the Funco Motorsports Pro Scale 8S 2WD Electric Sand Car, the WideMaxx Monster Truck, the X-Maxx Belted 4WD Brushless RTR 8S Monster Truck, the X-Maxx Ultimate, the X-Monster Chassis, the XRT VXL-8S, and the XRT Ultimate. You should consult your specific model's owner's manual to confirm the recommended spur gear ratio for your vehicle.
• What is the difference between different spur gear tooth counts? — Spur gear tooth count directly determines your vehicle's acceleration and top-speed balance. A higher tooth count (like this 50-tooth option) provides better low-end acceleration and climbing power on obstacles, whilst smaller tooth counts favour maximum velocity. Choosing the right ratio depends on your running environment—sand requires different gearing than track, and competitive racing requires different setup than casual bashing.
• Why should I upgrade to a steel spur gear? — Steel spur gears offer dramatically superior durability compared to nylon or plastic alternatives, particularly in high-performance brushless RC cars that produce extreme torque. The wide-face profile of this Traxxas gear distributes load more evenly, preventing tooth stripping and gear failure during hard acceleration, jumps, and high-speed impacts. For serious UK RC enthusiasts running 6S or 8S brushless systems, a steel spur gear is essential for reliability.
• Is this a genuine Traxxas part? — Yes, the TRX6448R is an authentic, factory-authorised Traxxas component manufactured to OEM specifications. When you purchase from an authorised UK Traxxas retailer like RC Model Shop, you can be confident you're receiving a genuine part with proper engineering tolerances and full compatibility guarantee.
• How often do I need to replace my spur gear? — With proper maintenance and use of quality lubricants, a steel spur gear like this can last many months or years of regular RC driving. However, aggressive driving, improper mesh setting, worn pinion gears, or impacts can accelerate wear. If you notice grinding noises, hesitation during acceleration, or visible tooth damage, it's time to replace the gear.
• What tools do I need to install this spur gear? — Installation requires basic tools including a hex driver set and potentially a spur gear puller or socket set, depending on your specific Traxxas model. Your vehicle's owner's manual will provide detailed installation instructions. If you're uncertain about the process, visit us at RC Model Shop where our experienced team can assist.
