I designed and built this external differential locking system to use on my custom Mini Buggy and ATV projects. In this video, you can see how the lock mechanism works and how smoothly it engages.

Watch the video and let me know what you think in the comments! Follow the page for more creative custom engineering projects. #OffRoadAdventure #CustomB
