This aluminium heavy duty differential locker is an RC-scale replacement made for the Axial Racing Yeti platform and supplied as a 1pc set bearing model YT050R. It is intended to upgrade the locker element inside the differential with a stronger aluminium component.
The write up emphasises correct fitment and tuning rather than claiming changes at vehicle level. The unit installs after disassembling the differential carrier using common hex drivers and bench tools. It alters driveline response to favour locked or limited-slip behaviour for rock racer and trail driving scenarios.
Install this aluminium locker when durability under heavy trail or rock use is a priority and you can carry out a basic gearbox teardown to fit and tune the differential behaviour.
