I just got my Rampage MT V2 up and running again, I just got a 26cc head kit nothing extreme, But on the first run taking it easy as possible, no hills or bumps just flat ground , I snaped the rear diff cup again, this was the diff cups that came in the V2 upgraded kit with the 3.5mm pins, My question is what are you guy doing to keep these cups from breaking now, i reinstalled the factory drive cups in the rear the 3.0 pin ones that came with the truck stock, but Im scared now to give the truck any kinda gas with the stock weaker cups for fear of breaking them also, will the V3 diff cups work on a v2 or is that a tottaly different setup ? thanks
