I hesitated before buying it because of price, but after finding a similar type jack at a pep boys I wasn't happy with the quailty so I popped for the K and L. Boy am I happy I did. This thing is heavy duty and is a one time purchase, it'll last me forever. Wide base, screw arm stays tight, no rattles, first rate quality for sure.
I added This K&L center jack to my bike lift so i could do full service on all my H-D Sporsters. From changing the tires or servicing of the brakes this center jack is watt every biker needs to do it all. Its really easy to operate and the quaility is excellent.
