Traxxas TRX8052 Spur Gear 39-Tooth 32-Pitch RC Crawler Spare Part

Overview

The Traxxas Spur 39-tooth (32-pitch) gear TRX8052 is an essential drivetrain component designed specifically for Traxxas TRX-4 scale RC crawlers and off-road vehicles. This precision-engineered spur gear is a genuine OEM Traxxas part, manufactured to exact specifications to ensure reliable performance and seamless compatibility with your TRX-4 model. Whether you're maintaining your RC crawler after extended use, upgrading your drivetrain, or replacing a worn component, this spur gear delivers the quality and durability you expect from Traxxas, the world's leading RC vehicle manufacturer.

If you own any of the popular TRX-4 models available in the UK RC market—including the Chevrolet K10 Cheyenne High Trail Edition, Ford F-150 Ranger XLT, 1972 Chevrolet K5 Blazer, 1979 Chevy Blazer, Nissan Pathfinder SE-V6, Land Rover Defender, 2021 Ford Bronco, or TRX-4 Sport variants—this spur gear is a crucial spare part to have on hand. RC enthusiasts who regularly bash, race, or crawl their vehicles know that maintaining genuine OEM parts is the best way to keep your RC car UK-ready and performing at its peak. This is a genuine Traxxas spare part, not a third-party alternative, ensuring it meets the exact engineering tolerances required for your TRX-4 transmission.

Spur gears are the primary drivetrain component that transfers power from the motor to the wheels through the transmission system. Over time, with regular use on challenging terrain, spur gears can wear, strip, or chip. Having a replacement Traxxas Spur 39-tooth gear on hand means you can quickly get back to driving rather than waiting for delivery during peak season. This is the kind of essential spare part every serious RC hobbyist should keep in their workshop or spare parts box.

Key Features

• Easy Installation — As a direct OEM replacement part, installation is straightforward for anyone with basic RC maintenance knowledge, requiring only standard tools and a few minutes to swap out the old gear.
• Long-Term Reliability — Investing in genuine Traxxas spares extends the lifespan of your RC crawler's transmission and prevents secondary damage to the pinion gear, motor, or differential components caused by worn or damaged spur gears.

Technical Performance

The Traxxas Spur 39-tooth TRX8052 is engineered with precision to maintain the exacting standards required for reliable RC crawler operation. As the primary driven gear in the TRX-4 transmission, the spur gear must withstand constant rotational forces whilst maintaining concentricity and tooth alignment to prevent slipping, binding, or noise. The 32-pitch specification refers to the gear's tooth module, which determines the tooth size and spacing; this 32-pitch standard is the correct specification for all TRX-4 models and ensures proper mesh with the pinion gear driven by the motor. The gear is constructed from durable materials selected to resist wear and chipping during aggressive crawling, rock hopping, and high-torque situations commonly experienced by RC crawlers on UK terrain. Whether you're traversing rocky trails, climbing vertical obstacles, or navigating loose gravel, this spur gear is engineered to deliver consistent, reliable performance. The precision manufacturing process ensures that the gear runs quietly and efficiently, minimising power loss and maximising the transmission of motor torque to the wheels. For RC enthusiasts who demand reliability and want to keep their TRX-4 running smoothly, using genuine Traxxas spare parts like this spur gear is the most cost-effective long-term approach to vehicle maintenance.

Frequently Asked Questions

• Is the Traxxas Spur 39-tooth gear compatible with all TRX-4 models? — Yes, this spur gear is compatible with a wide range of Traxxas TRX-4 models, including the Chevrolet K10 Cheyenne High Trail Edition (in red, blue, black, and metallic copper finishes), Ford F-150 Ranger XLT High Trail Edition (in brown, blue, and black), 1972 Chevrolet K5 Blazer (in blue and red), 1979 Chevy Blazer with clipless body (in black and red), Nissan Pathfinder SE-V6 3S (in red and silver), Land Rover Defender (in red, silver, green, and sand), 2021 Ford Bronco (in red, white, orange, and black), and TRX-4 Sport variants in various colours. If you own a TRX-4 model, this gear should be compatible, but we recommend checking your vehicle's documentation or contacting our team if you're unsure.
• What is the difference between a 39-tooth spur gear and other tooth counts? — The tooth count determines the gear ratio between the motor pinion and the spur gear. The 39-tooth configuration found in the TRX8052 is the standard specification for TRX-4 models and provides the correct balance of power delivery and top speed for trail crawling and rock crawling. Using a different tooth count would alter the vehicle's performance characteristics and is not recommended.
• How often should I replace my spur gear? — The lifespan of a spur gear depends on usage intensity, terrain, and driving style. Regular crawlers and basher users might replace their spur gear every 6-12 months of frequent use, whilst casual users may go longer. Signs of wear include visible tooth damage, chipping, unusual noise, or a noticeable loss of power transmission efficiency. Replacing a worn spur gear promptly prevents damage to the pinion gear and motor bearings.
• Is this a genuine Traxxas part? — Yes, the TRX8052 is an authentic, OEM Traxxas spare part, not a clone or third-party alternative. Genuine Traxxas parts ensure perfect compatibility, proper fit, and the durability you expect from the manufacturer. The product is supplied with the EAN code 0020334805201 and the official Traxxas part number TRX8052.
• What tools do I need to replace the spur gear? — Replacement requires basic RC maintenance tools including hex wrenches (Allen keys) and potentially a transmission housing tool, depending on your specific TRX-4 model variant. Traxxas provides detailed assembly instructions with most models, and our team can provide guidance if needed.
• Why is it important to use genuine Traxxas spares rather than aftermarket alternatives? — Genuine Traxxas parts are engineered to exact OEM specifications and tolerances, ensuring perfect mesh with complementary components, minimal noise, and maximum durability. Aftermarket or clone parts may have dimensional variations that cause binding, slipping, accelerated wear, or drivetrain damage. Using genuine spares protects your investment and keeps your RC crawler performing reliably.
