I'm not absolutely sure, but I think not, other than the sniper. I think we would have heard from someone if there were. I know of at least one guy in my town running Kongs, but he changed whls and hexs I believe ... spendy. I got a set of 4 Nem whls and tires ( new ) off e-bay for $50. I'll either pull the hexs off my Nem for the Gen or watch e-bay for a set. Rite now guys are bidding them up way high
