For RC enthusiasts across the UK seeking authentic replacement parts backed by manufacturer warranty and quality assurance, this is the component to choose.

The 32-pitch specification combined with the 22-tooth count makes this pinion ideal for TRX-4 platform vehicles including the popular Ford Bronco variants and Land Rover Defender models. If you own a ready to run RC crawler or are building a competitive machine, having genuine spare components on hand is essential. This hardened steel construction resists wear far better than standard gears, meaning fewer replacements and more time enjoying your RC experience.

Key Features

• Heavy-duty hardened steel construction — This pinion gear is manufactured from hardened steel rather than standard material, which significantly increases durability and wear resistance during extended driving sessions on rough terrain or in competitive racing environments, ensuring your investment lasts longer.
• 22-tooth specification — The 22-tooth count is precisely engineered for optimal power delivery and speed characteristics when meshed with compatible spur gears, providing the right balance of acceleration and top speed for crawler and off-road applications.
• 32-pitch gear standard — The 32-pitch specification ensures this pinion integrates seamlessly with OEM Traxxas drivetrain components, guaranteeing perfect mesh alignment, smooth power transmission, and elimination of backlash or grinding noises that plague poor-quality alternatives.
• Set screw retention — The integrated set screw design provides secure fastening to the motor shaft, preventing slippage under load and maintaining consistent performance even during aggressive acceleration or climbing steep obstacles.
• 3.2mm bore diameter — Machined to precise tolerances with a 3.2mm bore, this pinion fits standard Traxxas motor shafts perfectly, ensuring proper alignment and eliminating the vibration or noise that results from poor fitment.
• Genuine Traxxas component — As an official Traxxas part, this pinion gear is backed by manufacturer quality assurance and warranty, giving you confidence that you're purchasing an authentic component rather than a counterfeit or inferior copy.
• Wide vehicle compatibility — This pinion works across multiple TRX-4 platform models including the 2021 Ford Bronco in orange, black, red, and white variants, as well as the Land Rover Defender in green, sand, red, and silver finishes, making it a versatile spare parts solution.

Technical Performance

The Traxxas 22-T Pinion Gear represents precision engineering at its finest. The hardened steel material undergoes specialised heat treatment to achieve superior surface hardness compared to standard gears, directly translating to longer service life and more predictable performance in RC crawlers and scale trucks. The 32-pitch specification is an industry-standard measurement referring to the tooth spacing; combined with the 22-tooth count, this creates optimal gear ratios for Traxxas TRX-4 platform vehicles, which are renowned for their realistic crawling speeds and technical climbing ability. The 3.2mm bore diameter is machined to exacting tolerances, ensuring this pinion seats perfectly on motor shafts without excessive clearance or binding. When properly meshed with the spur gear, this pinion delivers smooth, vibration-free power transmission essential for maintaining steering control and traction during technical rock crawling or high-speed bashing. The set screw locking mechanism prevents unwanted rotation on the motor shaft, a critical feature that separates quality Traxxas components from budget alternatives. Unlike gears that strip or wear prematurely, the hardened steel construction maintains its tooth profile through hundreds of hours of demanding use, whether you're in the UK's challenging terrain or international competition. The engineering tolerances ensure this pinion works in harmony with the vehicle's gearbox and spur gear arrangement, maintaining the precise backlash specifications that keep the drivetrain running quietly and efficiently.

Frequently Asked Questions

• Is this pinion gear compatible with my Traxxas TRX-4 crawler? — Yes, this 22-T pinion is specifically engineered for TRX-4 platform vehicles. It's confirmed compatible with the 2021 Ford Bronco models (orange, black, red, and white) and the Land Rover Defender 4WD (green, sand, red, and silver). If you own one of these specific TRX-4 variants, this is the correct replacement or upgrade pinion. Always check your vehicle's manual to confirm compatibility before purchasing.
• Why choose hardened steel over standard gears? — Hardened steel undergoes heat treatment that increases surface hardness significantly, making the teeth far more resistant to stripping, chipping, or wearing down. For serious RC drivers, especially those running their crawlers regularly or in competitive environments, the durability advantage of hardened steel justifies the investment. You'll experience fewer gear failures, less downtime, and better overall reliability compared to standard gears.
• What is the 32-pitch specification and why does it matter? — Pitch is a standardised measurement of tooth spacing on gears; 32-pitch means the teeth are spaced to a specific standard that ensures perfect meshing with compatible Traxxas spur gears. Using a 32-pitch pinion with 32-pitch spur gears maintains the exact backlash and alignment your TRX-4 was designed for, preventing noise, slippage, and premature wear. Mixing pitch standards results in poor mesh and potential damage.
• Do I need tools to install this pinion? — Installation requires a small hex key or Allen wrench to tighten the set screw that locks the pinion onto the motor shaft. Most RC drivers already have these tools. We recommend checking your vehicle's manual for specific installation instructions and torque specifications to avoid over-tightening, which can damage the set screw or motor shaft.
• What's the difference between 22-tooth and other pinion sizes? — Pinion tooth count directly affects gear ratio and performance characteristics. A 22-tooth pinion paired with a specific spur gear size creates the gear ratio engineered into your TRX-4. Changing to a different tooth count alters acceleration, top speed, and torque characteristics. The 22-T specification is OEM for your vehicle, providing the correct balance of performance that Traxxas engineers designed in.
• How often should I replace my pinion gear? — With proper maintenance and the hardened steel construction of Traxxas components, you should expect many hundreds of hours of use before replacement becomes necessary. However, if you notice grinding noises, reduced acceleration response, or visible tooth damage, replacement becomes necessary. Regular inspection during maintenance checks will alert you to wear before failure occurs.
• Is this suitable for beginners? — This is a replacement component intended for users with some RC experience or who can follow installation instructions carefully. If you're completely new to RC cars, we recommend purchasing a ready to run RC crawler that comes with the pinion pre-installed. Once you've gained some experience, this genuine Traxxas replacement part will be an essential spare to have on hand.
