Overview
The Fastrax TRX-4 Brass Hex Wheel Hubs V2 +5mm (4) FTTX341BR represent a premium upgrade option for Traxxas TRX-4 scale crawlers across the UK RC hobby community. These brass hex wheel hubs deliver significant performance enhancements over standard plastic alternatives, making them an essential tune-up for serious RC car enthusiasts who demand improved handling, durability and ground clearance. Whether you operate a Chevrolet K10 Cheyenne, Ford F-150 Ranger, Chevrolet K5 Blazer, Nissan Pathfinder or Ford Bronco variant, these hubs will transform your crawler's on-trail performance and longevity.
Brass construction offers multiple advantages for 1/10 scale RC crawler owners. The added weight from brass provides superior mass distribution and improved traction on uneven terrain, whilst the material's inherent strength resists impacts and maintains precision fit tolerances that plastic simply cannot match. The +5mm offset specification positions your wheels further outboard from the chassis, resulting in a noticeably wider stance that enhances stability during rock crawling and technical terrain navigation. This is the V2 evolution of Fastrax's proven design, incorporating refinements developed from real-world user feedback and competitive crawling experience.
These are not bolt-on-and-forget components—they represent a thoughtful investment in your TRX-4's chassis dynamics and long-term reliability. Available now in the UK with free mainland delivery on orders over £99, these hubs are in stock and ready to elevate your ready to run RC crawler experience.
Key Features
- Brass Construction — The use of premium brass material provides superior durability and impact resistance compared to standard plastic hubs, ensuring your investment withstands the rigours of regular crawling, rock bashing and technical terrain work without cracking or deforming.
- +5mm Offset Specification — The additional 5mm outboard positioning widens your TRX-4's overall stance, delivering measurably improved stability and confidence through technical sections, whilst also enhancing visual presence and creating more aggressive proportions on your scale model.
- V2 Evolution Design — This second-generation hub incorporates design refinements based on extensive user feedback and competitive crawling experience, ensuring you benefit from the latest engineering optimisations and proven reliability enhancements.
- Precision Engineering — Brass hubs maintain exacting tolerances that prevent wheel wobble and uneven tyre wear, preserving your crawler's handling characteristics and tyre lifespan compared to looser plastic alternatives.
- Four-Piece Set — This package includes all four hubs required for a complete wheel replacement, eliminating the need for multiple purchases and ensuring consistent performance across all four corners of your TRX-4.
- Transmission Tune-Up Category — Classified as a transmission/drivetrain upgrade, these hubs directly influence weight distribution, traction delivery and overall crawling dynamics throughout your RC experience.
Technical Performance
The Fastrax TRX-4 Brass Hex Wheel Hubs V2 +5mm deliver measurable performance improvements through material science and precision engineering. Brass exhibits significantly higher density than the plastic hubs found in standard TRX-4 packages, creating lower centre of gravity and improved mass distribution that translates to better traction and stability during technical crawling sequences. The material's rigidity prevents the flex and deflection associated with plastic components, maintaining consistent wheel alignment and eliminating the tyre scrubbing and handling unpredictability that occurs when hubs deform under load. The +5mm offset places wheels 5 millimetres further away from the chassis centreline, widening the vehicle's footprint for enhanced rollover resistance on steep terrain and during extreme articulation. This wider stance also improves weight distribution across all four tyres during rock crawling manoeuvres, preventing weight concentration and the associated loss of traction. The V2 specification incorporates design refinements that improve hex-to-wheel interface reliability, reducing any potential for looseness or play that could develop during extended use. For TRX-4 owners seeking the ultimate in chassis dynamics, durability and technical terrain performance, these brass hubs represent genuine engineering advancement—not simply aesthetic customisation.
What's in the Box

Frequently Asked Questions
- What TRX-4 models are these brass hubs compatible with? — These Fastrax hubs are engineered for the full range of Traxxas TRX-4 crawlers, including the Chevrolet K10 Cheyenne High Trail Edition (red, metallic blue, brown, black and metallic copper variants), Ford F-150 Ranger XLT High Trail Edition (brown, blue and black), 1972 Chevrolet K5 Blazer High Trail Edition (blue and red), 1979 Chevy Blazer (black and red), Unassembled Chassis Kit, Nissan Pathfinder SE-V6 3S (red and silver), 2021 Ford Bronco (red, white, orange and black), Defender 4WD (silver, red, sand and green), and TRX-4 Sport variants (all colours). Ensure your specific model is listed in the compatibility section before purchase.
- Do I need to purchase anything else with these brass hubs? — Yes, the critical additional requirement is longer stub axles part number FTTX322. The +5mm offset specification requires these extended stub axles to achieve proper fit and function. Do not attempt installation without obtaining these axles separately, as standard stub axles will not provide adequate engagement with the +5mm offset hubs.
- What is the difference between +5mm and +3mm offset hubs? — Fastrax also manufactures these brass hubs in a +3mm offset variant (FTTX340BR). The +5mm specification offers greater stance width and enhanced stability for extreme terrain work, whilst the +3mm provides a more subtle stance adjustment suitable for users who prefer a narrower footprint or stock-adjacent handling characteristics. Choose +5mm for maximum terrain confidence and dramatic visual impact, or +3mm for a more understated upgrade approach.
- Why are brass hubs superior to my stock plastic hubs? — Brass offers several critical advantages over plastic. It resists impact damage and maintains precise tolerances indefinitely, preventing the gradual deformation and wheel wobble that develops in plastic hubs during extended use. The added mass improves traction and stability, whilst the material's rigidity eliminates flex that compromises handling precision. For serious crawlers and frequent users, brass hubs represent a one-time investment that delivers years of superior performance.
- Are these hubs suitable for beginners? — Whilst these hubs are not complex components, they represent an intermediate-level upgrade best suited to TRX-4 owners with basic RC maintenance experience and understanding of their model's specifications. Beginners running stock TRX-4 ready to run systems may prefer to gain foundational experience before exploring offset and material upgrades. However, if you are upgrading a stock crawler and obtain the required FTTX322 stub axles, installation is straightforward for anyone with basic RC knowledge.
- How much do these hubs improve handling on technical terrain? — The performance improvement is genuinely noticeable, particularly on steep rock gardens and extreme articulation sequences where the wider stance and improved weight distribution provide measurably better traction and rollover resistance. You will experience enhanced confidence during technical crawling, reduced tyre scrubbing, and improved consistency across repeated terrain challenges. The brass material also eliminates the tyre wear irregularities and handling inconsistencies associated with plastic hub flex.
