INJORA Brass Hex Hub 15mm for 1/10 RC Crawler – 12mm Hex Drive Adapter (Set of 4)
INJORA Brass Hex Hub 15mm for 1/10 RC Crawler – 12mm Hex Drive Adapter (Set of 4)
These INJORA brass hex hubs serve as a direct replacement or extension for your 1/10 RC crawler's wheel mounting. Each set includes four 15mm-thick adapters with a 12mm hex drive, made from solid brass with a black hard coating to resist corrosion and abrasion. The added weight helps lower the vehicle's center of gravity for improved stability during technical climbs.

Why add unsprung weight with brass hubs?
In rock crawling, additional unsprung weight on the wheels can improve traction by keeping the tires planted. Brass is denser than aluminum or plastic, so these hubs concentrate mass exactly where it helps most. The chamfered edges and etched INJORA logo add visual detail, while the black coating protects against the elements.
Compatibility and installation
These hubs are designed for 1/10 scale RC crawlers that use 12mm hex wheel rims. Common compatible models include the Axial SCX10 90046, SCX10 II, and D90. They function as both a replacement hub and a wheel spacer, widening the track width slightly for better stability. Installation requires removing the existing wheel hex and replacing it with this brass unit. No additional spacers needed.
What are the practical benefits?
- Solid brass construction resists wear and deformation.
- Black hard coating prevents corrosion and reduces glare.
- Heavier than stock plastic or aluminum hubs, lowering CG.
- Extends wheel stance for increased stability.
Priced per set of four, enough for one complete vehicle.
Common questions
Are these compatible with 1/10 Traxxas TRX-4?
The supplied data indicates fitment for 12mm hex rims on 1/10 crawlers like Axial SCX10 and D90. Compatibility with models not listed is not specified.
Can I use these as a wheel spacer?
Yes, they function as an extension by adding 15mm to the wheel hub width. This widens the track.
What is the weight per hub?
Approximately 14.25g each (57g total set of 4).
Do I need any additional hardware?
