Hmmm... this is interesting, i was hoping that my x1crt diffs would fit in the hybrid bulks. Maybe not?
The jammin diffs will be exact same size as the 777 and hot bodies diffs, there all based off of the kyosho gears any way..
The titan on the other hand (all 9.5 based ofna buggies) have a larger diff cup and if not mistaken a greater circumference then the kyosho based diffs.
