Since the Slipper was designed as a de-coupled mechanism, the Ball diff will work on the truck. It also works much better than any slipper set-up, de-coupled or pinned, basket or not. Both Mantis and I can attest to that.
We have been testing a ball diff for a while as well. This has already been discussed with Marcus too. We both sort of started working on the project at the same time, however it takes us longer to release the product as it will include a manufactured spur and machined slipper hubs. Expect our center diff to be ready around Mid January.
