Overview
The Traxxas Wheel hubs, 7mm hex (brass) (4 pcs) / axle pins (8 pcs) TRX9750X is an essential upgrade and replacement part for owners of the Traxxas TRX-4M series of 1/18 scale RC crawlers and trail trucks. Whether you're running a Ford Bronco, Land Rover Defender, Chevrolet K10, or Ford F-150 in the TRX-4M or TRX-4MT range, these premium brass wheel hubs are designed to deliver improved performance, durability and reliability during intense off-road adventures. For RC enthusiasts across the UK looking to maintain, upgrade or repair their trail crawler, this is a crucial component that ensures your wheels stay securely attached and perform optimally on challenging terrain.
Brass construction offers significant advantages over standard materials when it comes to weight distribution and durability in small-scale RC vehicles. These wheel hubs are specifically engineered to fit the 7mm hex drive system used throughout the TRX-4M platform, ensuring perfect compatibility and reliable fitment every time. The inclusion of eight axle pins means you'll have spare fasteners on hand for maintenance, repairs, or customisation projects, giving you peace of mind that your crawler will always be ready for the next adventure.
RC car enthusiasts in the UK know that quality replacement parts from authorised Traxxas suppliers are the foundation of a well-maintained, high-performing machine. The TRX9750X represents genuine Traxxas engineering and precision manufacturing, delivering the exact fit and performance characteristics your TRX-4M demands. Whether you're basking in countryside trails, tackling garden obstacles, or competing in organised RC crawler events, having genuine Traxxas parts ensures your investment continues to perform at its peak.
Key Features
- Brass Material Construction — The wheel hubs are manufactured from brass, a material chosen specifically for its superior strength-to-weight ratio and durability in demanding off-road conditions. Brass hubs maintain structural integrity under the stresses of rock crawling, side slopes and technical terrain whilst remaining lightweight enough to preserve the responsive handling characteristics of your 1/18 scale RC crawler.
- 7mm Hex Drive Compatibility — These hubs feature a precise 7mm hexagonal drive that perfectly matches the standard drivetrain specification of all TRX-4M series models, including the Ford Bronco, Land Rover Defender, Chevrolet K10 and Ford F-150 variants. This ensures rock-solid fitment and reliable torque transmission from your drive shafts to your wheels with zero play or wobble.
- Complete Four-Hub Set — The package includes four wheel hubs, one for each corner of your crawler, eliminating the need to purchase multiple sets or hunt for individual components. This is the ideal solution whether you're replacing worn hubs, upgrading from standard components, or building a complete new TRX-4M setup from scratch.
- Eight Spare Axle Pins Included — Beyond the four hubs, you receive eight precision-machined axle pins that secure the hubs to your vehicle's axle shafts. Having double the number of spare pins means you'll always have replacements on hand if a pin becomes damaged, lost or bent during rigorous trail running or maintenance sessions.
- Premium Traxxas Quality — These components are manufactured to Traxxas' exacting specifications and quality standards, ensuring that every hub and pin meets the precision tolerances required for flawless performance. When you buy genuine Traxxas parts like the TRX9750X, you're investing in reliability and longevity rather than cheaper alternatives that may compromise your crawler's performance.
- Essential Upgrade for Trail Crawlers — Brass hubs are widely recognised in the UK RC crawler community as a superior upgrade choice compared to plastic alternatives, offering better durability and improved weight distribution that enhances crawling characteristics and traction on technical terrain.
Technical Performance
The TRX9750X wheel hubs represent a critical drivetrain component in the TRX-4M platform, which is Traxxas' premier 1/18 scale rock crawler designed for serious trail enthusiasts and competitive crawlers. The brass construction provides exceptional durability compared to lighter alternatives, maintaining dimensional accuracy and structural integrity even after hundreds of hours of trail running across rocks, logs, water crossings and steep slopes. The 7mm hexagonal drive interface is the industry-standard specification for small-scale RC crawlers, and these Traxxas hubs deliver the precision engineering required for flawless engagement with your drive shafts. The axle pins included in this package are precision-machined to exact tolerances, ensuring they seat firmly in the hub bore without excess play whilst remaining easy to install and remove for routine maintenance. The brass material is particularly valued in the competitive RC crawler world because it maintains its structural properties across a wide range of temperatures and conditions, from cold UK winters to hot summer sessions on exposed terrain. Whether your TRX-4M Ford Bronco, Land Rover Defender, Chevrolet K10 or Ford F-150 is used for casual weekend trail running or intensive competition, these hubs will provide the reliability and performance your crawler deserves.

Frequently Asked Questions
- Are these wheel hubs compatible with all TRX-4M models? — Yes, the TRX9750X hubs are compatible with the entire Traxxas TRX-4M range, including the Ford Bronco (all colours: blue, red, orange, black, white, Area 51), Land Rover Defender (all colours: green, light blue, pink, silver, tan, black), Chevrolet K10 High Trail (blue, red, black), Ford F-150 High Trail (black, brown, blue), and both the TRX-4MT K10 and F150 Monster Truck variants (red, black, blue). If you own any TRX-4M series crawler, these hubs will fit perfectly.
- Why should I choose brass hubs over standard plastic hubs? — Brass hubs offer superior durability and strength compared to plastic alternatives, particularly important when crawling over rocks, logs and rough terrain. The brass material maintains its structural properties over time and temperature variations, resists wear better than plastic, and provides improved weight distribution that enhances your crawler's handling and traction characteristics on technical sections. For serious UK RC crawler enthusiasts, brass hubs are considered a worthwhile upgrade investment.
- What are the axle pins used for? — The axle pins are precision fasteners that secure the wheel hubs to your crawler's axle shafts, holding them in place whilst allowing controlled rotation. The eight pins included in this package are spares, meaning if a pin becomes damaged, bent or lost during trail sessions or maintenance, you'll have replacements immediately available without needing to wait for a new order.
- How often will I need to replace these hubs? — Brass hubs are designed for long-term durability and should last through hundreds of hours of crawling if properly maintained. However, if you notice excessive wear, cracking, or loss of dimensional accuracy, replacement is straightforward using these genuine Traxxas components. Regular inspection during routine maintenance will alert you to any potential issues before they affect your crawler's performance.
- Are these genuine Traxxas parts? — Yes, the TRX9750X is an official Traxxas component manufactured to the brand's exacting specifications. When you purchase from an authorised UK Traxxas retailer like RC Model Shop, you can be confident you're receiving genuine parts with full manufacturer compatibility and warranty support.
- Will these improve my TRX-4M's performance? — If you're replacing worn or damaged hubs, these genuine Traxxas components will restore your crawler to optimal performance. If you're upgrading from plastic hubs, brass alternatives will provide improved durability and enhanced weight distribution that many UK crawlers report as beneficial to handling and traction on technical terrain.
