I’ve been running the latest incarnation of Atomic’s ball diff since the release of the MRV and was happy to see that the company is now including a machined spur and a set of aluminum dust guards with the MRX Ultra v1.1 kit. These are welcome upgrades that turn an already good diff into an excellent one.
In addition to sanding the plates, the only other mod that I often do is to swap out the 3x6x2.5mm bearing for a thrust bearing. In this case, I’m using one from Reflex.
