INJORA Brass Wheel Hex Hub 9mm Black Coating for Axial SCX10 PRO SCX10 III UTB10 Upgrade

This INJORA Wheel Hex Hub is a brass wheel adapter designed for 1/10 RC crawlers like the Axial SCX10 PRO, SCX10 III, and UTB10. It uses a 9mm hex width with a black hard coating and chamfered edges. The CNC-machined brass construction helps extend wheel stance for improved stability.

What makes this INJORA hex hub different from stock?

Stock hex hubs on many RC crawlers are made of plastic or lower-grade metals. This INJORA unit uses solid brass, which adds weight exactly where it helps most: low and centered on the wheel hub. The extra mass lowers the center of gravity, which can improve traction on off-camber sections. The black hard coating is more than cosmetic it resists corrosion and abrasion from rocks and dirt. Chamfered edges reduce snagging on obstacles and give the crawler a cleaner look.

How to install the wheel hex hub

Installation is straightforward. First, remove the original wheel hex hub from your RC crawler. Align the new INJORA hub with the wheel, then secure it using the provided screws. Tighten the screws firmly but avoid over-tightening, as brass can be softer than steel. The chamfered edges make alignment easier during installation.

Frequently asked questions

• Is this compatible with other 1/10 crawlers? The manufacturer states suitability for Axial SCX10 PRO, SCX10 III, and UTB10. Other models may require checking wheel hex size and offset.
• Does the black coating wear off over time? The black hard coating is designed to prevent corrosion and resist abrasion. Some wear can occur with heavy use on rough terrain.
• What tools are needed for installation? The kit includes screws. A small cross-head screwdriver or hex driver (depending on screw type) is typically required.

Why brass for wheel hubs?

Brass is denser than aluminum or plastic, so each hub adds significant unsprung weight. This weight lowers the vehicle's center of gravity and improves traction on challenging climbs and side-hills. The CNC machining ensures each hub is exactly 9mm thick, so your wheel offset is consistent side to side. The black coating also helps the hubs blend with dark rims and tire sidewalls.
