High Lifter Products’ PEN-Lock Differential Lever Locking Assembly was conceived by Kawasaki Team Green rider and 11-Time GNCC Champion, Mike Penland. This affordable upgrade enables riders to engage the front differential, and at the push of a button, secure the differential into the locking position until the handle is pressed once again to disengage the PEN-Lock. The device is similar in function to many parking brake systems that come standard on ATVs - squeeze the handle, engage the lock, and the handle is locked until it is squeezed once again. The PEN-Lock is machined from very attractive and durable T-6061 billet aluminum and the locking button is stainless steel The PEN-Lock is a direct bolt-on modifications with easy-to-read instructions and installation pictures provided.
