I've a Creeper too, RcBro/FLM lockers in the axles, it's on my blog on the "other forum". Haven't run it in a looooong time since putting a TCS tuber frame (for the AX10) on it, still new. Did really well for just running a Novak 55T in it and stock tires, plenty of flex. Guess I need to dig it out again soon.
