Technical Performance
Wheel hexes are precision components that transfer driving force from your RC car's driveshaft directly to your wheels. The 12mm diameter specification is the standard configuration for ARRMA's 1/16 scale platform, providing the optimal balance between structural strength and lightweight performance. Metal construction in wheel hexes offers several advantages over plastic alternatives: superior load-bearing capacity, enhanced resistance to stripping under high-torque conditions, and improved longevity through countless drive sessions. The engineering tolerances in ARRMA's genuine hexes ensure they maintain their circular geometry and fitting surface integrity even after extended use. For RC hobbyists who regularly take their models off-road or participate in competitive racing, metal wheel hexes represent the difference between enjoying consistent performance and experiencing mid-session failures due to hex deterioration. The dimensional precision of these components means they'll accept your wheel hub connections smoothly whilst maintaining the tight tolerances necessary for predictable handling. Whether you're running your 1/16 Mini Kraton 3S through muddy terrain, across rocky tracks, or on tarmac circuits, these metal hexes provide the structural foundation upon which reliable, enjoyable RC driving depends.

Frequently Asked Questions
- Are these metal wheel hexes genuine ARRMA parts? — Yes, the Z-ARA-3118 is an official ARRMA replacement component manufactured to the same specifications as the parts included with new ARRMA 1/16 Mini Kraton 3S models. Purchasing genuine ARRMA parts ensures compatibility, performance consistency, and warranty compliance.
- Which ARRMA models are these wheel hexes compatible with? — These 12mm metal wheel hexes are specifically designed for ARRMA 1/16 Mini Kraton 3S vehicles, compatible with all colour variants including the blue (C-ARA2508ST1), red (C-ARA2508T1), and teal (C-ARA2508ST2) models. If you own one of these Mini Kraton 3S variants, these hexes will fit perfectly without modification.
- Why would I need replacement wheel hexes? — Wheel hexes wear out through normal use as they transmit rotational force from your driveshaft to your wheels. They can also become damaged through impacts, rough terrain, or high-torque driving situations. Having spare wheel hexes allows you to maintain your RC car without extended downtime waiting for parts to arrive.
- What's the difference between metal and plastic wheel hexes? — Metal wheel hexes provide superior durability, superior resistance to stripping, and greater structural strength compared to plastic alternatives. Whilst plastic hexes may be lighter, metal hexes excel at handling the torque and stress that modern brushless RC motors generate, making them the preferred choice for serious RC enthusiasts.
- Do I need any tools to install these wheel hexes? — Installation requires basic RC maintenance tools including an appropriate hex key or Allen wrench sized for your wheel hub set screws. The process is straightforward: remove the wheel, unscrew the old hex from the driveshaft, install the new metal hex, and reattach the wheel.
