The RR010X/1215 28-piece set is made to work with Axial hub interfaces, replacing or extending stock hexes to change wheel offset and broaden the vehicle track for better cornering stability.
Bodies are machined from brass to introduce additional wheel-end mass, listed at approximately 11g per adapter, and the 15mm width closes up the wheel-to-hub gap compared with thinner hexes for a firmer fit on uneven ground.
Fitment is straightforward using the supplied hardware; the kit groups Delrin rings, pins, washers, screws and shims so you can swap them in on compatible models without sourcing extra parts.

If you want a quick way to widen stance and add wheel-end weight, these 15mm brass hex adapters install with the included hardware and help control wheel movement on rough trails.
