you shouldn't have any probs with only 4 cells

yeh as soon as i added 2 cells, and locked my diff, my plastic left cup just practically melted. that guy on ebay sells titanium ones for even more, 50$ ... which is ridiculous for such a small part.

I definatly see a NEED for the parts. I just don't see the cost justification. This is only my opinion though. It may be very worth the money to others, and if I ever add more cells to my xmod and have problems with the cups, I may also justify this cost. I have a feeling though that these won't be the only ones offered.
I must commend craftsman here for atleast taking the time and putting in the effort in making these for those who NEED them.

even with four cells... i too have found a way to destroy my rear cups. then again i am a fool to have ramped my poor lil rsx over my truck right? lol.... yeah... a friend and I decided it would be cool to build a ramp out of boxes from my last move and jump the xmods.... I tell ya what... these lil boogers can fly! upon landing... on my landing ramp.... my rear axle cup chiped.... so yeah... kinda blows. my only fix was to make the RSX front wheel drive. worked like a charm!!!
