Pro-Line Vice CrushLock 2.6" Monster Truck Wheels literally crush the tire beads together and narrow up 2.6" tires for extreme mud performance. CrushLock style wheels are a popular wheel upgrade in full-size mudding and now you can have the same thing in a smaller scale! These wheels pair perfectly with Pro-Line's licensed Interco Black Mamba 2.6" Mud Tires (PRO10181-00) for the ultimate in mud flinging performance. The Vice CrushLock wheels include Pro-Line's innovative 6x30 Removable Hex system allowing for multiple hex size and offset options (sold separately) with narrow and wide 12mm hexes included as standard.
