Yeah Racing 12mm Aluminum Hex Adaptors (Blue) (4) (15mm Offset)

Yeah Racing 12mm Aluminum Hex Adaptors. These optional hexes are intended to add track width to your RC rock crawler. With a wider track width, you can also increase the chassis flex due to a leverage effect of being able to put more force on the outer wheel. This translates to more grip during climbing. Package includes four hex adapters with grub screws.

NOTE: This will fit wheels with a center hole of at least 5mm.
