DMS brings you the strongest diff lock upgrade avalible for the KRX 1000. Nothing brings a riding trip to an end quicker than exploding the factory powdered metal gear. This commonly destroys the diff side cover, speed sensor and in worst case scenarios the diff case itself (which can't be purchased separatly). 
The DMS diff lock gear upgrade is CNC machined from 300m steel and heat treated with a propritary process to provide the best tensil strength for gears under high load. The installation process is really straight forward and requires no special tools.
