imco scx seems to have a strong upper but when coupled to the imco sc lower, the lower might be the weak point. anyone know if the max machine workx billet 2002-x2 will bolt on to the imco scx upper. i believe the mmw lower is a stronger lower than the imco sc and faster than the imco scx lower. any ideas? seems like this would make a good combo if possible.

Does the max lower use the XR gears in it? If so that is the weak point.
It should bolt on if that lower will bolt to an XR upper. You will need the special coupler to do it though.

Other than less case flex from the billet case and I have been told that somehow max worx is using some kind of double bearing set-up on vert shaft (not sure that is a real problem) those bravo lower gears are still a expendable wear item,Smitty

I have to agree the lower gear set is the problem with all the drives, merc or after market they all use the same thing .....................For now
