Traxxas Wheel Hubs 7mm Hex Steel 4 Pack with Axle Pins TRX9750A

Overview

The Traxxas Wheel hubs, 7mm hex (steel) (4 pcs) / axle pins (4 pcs) TRX9750A are genuine replacement parts designed specifically for the TRX-4M range of 1/18 scale RC trail trucks. Whether you're a dedicated RC enthusiast in the UK looking to maintain your Traxxas TRX-4M, or you've damaged a wheel hub during an off-road adventure and need a quick replacement, these steel hubs offer the durability and reliability you expect from Traxxas genuine parts. This is an essential tune-up option for anyone running a TRX-4M Ford Bronco, Land Rover Defender, Chevrolet K10, Ford F-150, or TRX-4MT Monster Truck variant.

Steel wheel hubs are a popular upgrade choice among RC car UK enthusiasts because they provide significant weight benefits when positioned lower on the vehicle, which improves overall handling characteristics and weight distribution. The 7mm hex connection ensures perfect compatibility with your TRX-4M's drivetrain, and the inclusion of axle pins means you have everything needed for a complete wheel assembly replacement or upgrade. These are genuine Traxxas parts, manufactured to exacting standards and tested to perform reliably in all conditions, from casual backyard bashing to serious trail running.

If you've been exploring ready to run RC vehicles and want to enhance your TRX-4M's performance and durability, these wheel hubs represent an affordable and practical investment. Available now from RC Model Shop, they're in stock and ready to ship to you across the UK.

Key Features

• Steel Construction — These wheel hubs are manufactured from steel rather than plastic or alloy, providing exceptional durability and strength that resists damage from impacts and rough terrain, making them ideal for serious trail driving and demanding off-road conditions.
• 7mm Hex Interface — The 7mm hex connection is the standard fitment for TRX-4M models, ensuring perfect compatibility and secure connection to your vehicle's driveshaft without any wobbling or play.
• Complete Assembly Package — Each set includes four wheel hubs plus four axle pins, giving you everything needed to replace all four wheels or perform a complete hub upgrade on your TRX-4M, without needing to source additional components separately.
• Genuine Traxxas Parts — These are authentic Traxxas OEM (Original Equipment Manufacturer) parts, not aftermarket copies, which means they're engineered to exact specifications and guaranteed to work perfectly with your vehicle.
• Weight Distribution Benefits — As confirmed by user reviews, steel hubs provide a significant amount of weight positioned lower on the vehicle, improving the centre of gravity and enhancing overall handling dynamics and stability during trail running.
• Affordable Performance Upgrade — Despite offering genuine Traxxas quality and durability, these wheel hubs remain fairly cheap and readily available, making them an accessible way to upgrade or maintain your RC car UK investment.

Technical Performance

The Traxxas Wheel hubs, 7mm hex (steel) represent a straightforward yet effective performance upgrade for the TRX-4M family of 1/18 scale RC trail trucks. The steel construction provides a significant material upgrade over standard plastic hubs, offering superior impact resistance and longevity during intensive off-road use. The 7mm hex connection is precision-engineered to tolerances that ensure smooth, reliable engagement with your vehicle's driveshaft, eliminating any slop or play that could cause premature wear or loss of control precision. The inclusion of four axle pins with each set ensures that you have redundancy and spares on hand, as these small but critical components can occasionally work loose during vigorous driving sessions. The engineering philosophy behind these hubs prioritises durability and weight optimisation; by positioning additional mass lower on the vehicle through the use of heavier steel components, the overall centre of gravity is lowered, which directly improves handling response, reduces body roll during cornering, and enhances traction when traversing uneven terrain. This is particularly valuable for TRX-4M owners who use their vehicles for serious trail running or competition, where every fraction of a gram and every millimetre of height adjustment contributes to overall performance. The steel material also offers superior thermal stability compared to plastic, meaning the hubs maintain their dimensional accuracy and strength even after extended driving sessions in warm weather conditions. These parts are designed and manufactured in the USA by Traxxas, a company with more than 30 years of experience in radio control vehicles, which means the engineering and quality control standards are consistently high. They're compatible with the full TRX-4M range, including the Ford Bronco RTR in multiple colours (Blue, Red, Orange, Black, White, and Area 51), the Land Rover Defender RTR in six colour options (Green, Light Blue, Pink, Silver, Tan, and Black), the Chevrolet K10 High Trail Truck in three colours (Blue, Red, and Black), the Ford F-150 High Trail Truck in three colours (Black, Brown, and Blue), and both the TRX-4MT Monster Truck variants in K10 and F150 configurations available in Red and Black.

Frequently Asked Questions

• What is the 7mm hex connection, and why does it matter for my TRX-4M? — The 7mm hex is the industry-standard drivetrain connection used on TRX-4M models and many other RC vehicles. It's a hexagonal socket on the driveshaft that your wheel hub slides onto, ensuring a secure, locked connection that transmits power from your motor to your wheels without any slipping or play. The 7mm specification refers to the width across the flats of the hex, which must match exactly for proper fitment.
• Will these steel wheel hubs make my TRX-4M faster? — Steel wheel hubs don't directly increase speed, as they're a suspension and drivetrain component rather than a power delivery system. However, they do improve overall vehicle handling and stability by lowering the centre of gravity, which means you can drive more aggressively through corners and rough terrain without the vehicle becoming unstable, potentially allowing you to maintain higher speeds over technical ground.
• Are these genuine Traxxas parts or cheap aftermarket copies? — These are 100% genuine Traxxas OEM parts, manufactured to Traxxas specifications in the USA. You can verify authenticity through the EAN code (020334975058) and the official Traxxas part number TRX9750A. Genuine parts guarantee perfect compatibility and reliability.
• Do I need special tools to install these wheel hubs? — Installation should be straightforward for anyone with basic RC maintenance experience. You'll need standard tools like a hex key set and possibly a small hammer or mallet to press the hubs onto the axle pins, but no specialised equipment is required.
• What is the difference between steel and plastic wheel hubs? — Steel hubs are significantly heavier and more durable than plastic alternatives, which means they provide better weight distribution and lower the vehicle's centre of gravity for improved handling. However, they're also more costly. Plastic hubs are lighter and cheaper but wear out faster under heavy use and provide no weight distribution benefits. Steel is the preferred choice for serious trail runners and bashers who want maximum durability.
• How do these hubs compare to alloy or aluminium alternatives? — The sources provided discuss only the steel construction of these hubs, so specific comparisons with alloy or aluminium variants cannot be made. However, steel is renowned in RC circles for combining strength, weight, and affordability in a single package.
• Which TRX-4M models are compatible with these hubs? — These hubs are compatible with all TRX-4M variants, including the Ford Bronco (all colours), Land Rover Defender (all colours), Chevrolet K10 High Trail Truck, Ford F-150 High Trail Truck, and both TRX-4MT Monster Truck models. If you own a TRX-4M, these hubs will work with your vehicle.
