Overview
The ARRMA Aluminum Wheel Hex 17mm, 16.5mm Thick, Black (2) is an essential upgrade for owners of ARRMA RC vehicles across multiple scales and model ranges. These precision-engineered wheel hexes provide a strong and secure wheel fitting that is critical for maintaining performance and reliability during high-speed runs and aggressive driving. Whether you are piloting a 1/7 scale monster truck like the Big Rock or Mojave, a 1/8 scale speed truck such as the Kraton, or the legendary Notorious stunt truck, these aluminium hexes deliver the durability and consistency that serious RC enthusiasts demand. Available as a set of two, these components represent genuine ARRMA factory parts designed to meet the exact specifications of your vehicle, making them the ideal choice for replacement, upgrade or maintenance.
If you are serious about RC car performance in the UK, understanding the importance of quality drivetrain components is crucial. The wheel hex is the critical interface between your drive shafts and wheels, and using precision-manufactured parts ensures that power is transferred efficiently without wobble, play or inconsistency. ARRMA's reputation for producing high-performance brushless RC vehicles across scales from 1/8 to 1/7 is built on attention to detail in every component, including these wheel hexes. Whether you are a weekend basher enjoying your brushless RC truck on rough terrain, a track competitor pushing for lap time improvements, or someone maintaining their ready to run RC vehicle to factory specifications, having quality replacement hexes in your spares box is essential.
Black anodised aluminium construction gives these hexes a stealth, professional appearance whilst delivering genuine functional benefits. The anodised finish provides increased durability against the rigours of outdoor RC driving, protecting the aluminium from corrosion and wear. These parts fit numerous ARRMA models including the 1/7 Big Rock 6S, Fireteam 6S buggy, and Mojave 6S desert truck, as well as 1/8 scale vehicles such as the Kraton, Notorious and Talion speed trucks. The 17mm hex size is standard across these ARRMA platforms, and the 16.5mm total depth ensures perfect fitment without modification.
Key Features
- Precision manufactured aluminium construction — The hexes are engineered with tight tolerances to ensure consistent fit and secure wheel mounting across your RC vehicle, which directly impacts handling precision and reduces unwanted play in the drivetrain that could compromise steering response and straight-line stability.
- Reduced vehicle weight through aluminium material — By using lightweight aluminium rather than heavier steel alternatives, these hexes contribute to lower overall vehicle mass, which improves acceleration, reduces inertia and helps your brushless RC motor work more efficiently, particularly important on high-performance models like the Kraton 6S and Notorious 6S.
- 17mm hex size with deep hex profile — The deep profile design maximises the contact surface area between the hex and your wheel, increasing structural support and resistance to stripping or failure under extreme torque loads that can occur during aggressive acceleration or impacts on off-road terrain.
- Black anodised finish for durability and aesthetics — The anodised coating provides genuine protective benefits against corrosion from moisture and dirt whilst delivering that distinctive stealth look that complements modern ARRMA vehicle designs and appeals to serious RC enthusiasts who want their vehicles to perform as well as they look.
- 16.5mm total depth for perfect fitment — The precise depth specification ensures these hexes fit seamlessly into your existing ARRMA vehicle configuration without requiring any modifications, spacers or adjustments, making installation straightforward and reliable.
- Supplied as a pair — Each package contains two hexes, providing a complete set for one axle or allowing you to maintain spares for both front and rear, which is practical for drivers who run multiple sessions or competitive racing where reliability is paramount.
Technical Performance
These ARRMA aluminium wheel hexes represent the engineering standards that ARRMA applies across its entire range of brushless RC vehicles, from the 1/7 scale Big Rock and Mojave desert trucks down to the compact but powerful 1/8 scale Kraton speed truck. The hexes are manufactured to precision specifications that ensure zero play and consistent hub-to-wheel alignment, which is critical for maintaining the handling characteristics that ARRMA engineers have calibrated into each vehicle platform. The use of aluminium rather than plastic or inferior materials means these hexes can withstand the extreme torque loads generated by 6S LiPo-powered brushless motors without deformation or stress cracking. The 17mm hex size is the industry standard across modern ARRMA platforms, and the deep profile design maximises the engagement surface, reducing the risk of stripping that can occur with shallow hex profiles under high-stress conditions. The black anodised coating is not merely cosmetic; the anodisation process creates a hard oxide layer on the aluminium surface that resists wear, corrosion and UV degradation, extending the service life of these components significantly compared to bare aluminium. The 16.5mm total depth is engineered to integrate perfectly with ARRMA's wheel designs and drivetrain geometry, ensuring that these hexes function as intended without introducing alignment issues or vibration.

Frequently Asked Questions
- Which ARRMA vehicles use these 17mm wheel hexes? — These hexes are designed as standard parts for a wide range of ARRMA vehicles including the 1/7 Big Rock 6S RTR, Fireteam 6S RTR buggy, Mojave 6S RTR and Mojave 6S EXB roller, as well as 1/8 scale models such as the Kraton 6S RTR, Kraton 6S roller, Kraton 6S EXB RTR, Notorious 6S RTR and Talion 6S RTR. Check the product fitments list to confirm your specific model is compatible.
- Why would I need replacement wheel hexes? — Wheel hexes are wear items that can become damaged or loosened through normal use, particularly in aggressive driving conditions or after impacts. Having replacement hexes ensures you can maintain your vehicle's performance and handling characteristics without having to source alternative parts that might not fit as precisely.
- Are these wheel hexes suitable for beginners? — Yes, whilst these are quality precision components, they are simple replacements that require no special knowledge or tools to install. If your existing hexes need replacing, these ARRMA originals are the straightforward choice, and any RC enthusiast of any experience level can swap them over.
- What is the difference between aluminium and plastic hexes? — Aluminium hexes like these offer significantly better durability, strength and longevity than plastic alternatives. They resist deformation under heavy load, maintain their dimensional accuracy over many uses, and the anodised finish provides superior corrosion resistance, particularly important if you drive in wet conditions or near salt water common to many UK locations.
- How do I know if my hexes need replacing? — If you notice play between your wheel and hub, wobbling during rotation, difficulty getting wheels to sit true, or if you have experienced an impact that affected one side of your vehicle, it is time to replace your hexes. Installing these quality ARRMA replacements will restore your vehicle's handling precision.
