I installed the MIP CVD kit from Tower, and after running with them for about 40 min, I stripped either my idler or diff gear (I'm yet to disassemble) both of which are still stock. Am I just looking for more broken gears by installing the CVDs? The stock dog bone setup was seeing its age(starting to twist) which caused the upgrade. Would it be recommended to upgrade the tranny parts to a ball diff offered by traxxas [link=http://www.buytraxxas.com/product_info.php?cPath=4_717&products_id=1239]here[/link] and a metal idler if they make one??? Plz help

Thanks
