There is another solution, but unfortunately there is not a manual to electric conversion kit for the HappiJac 4160. You would need to upgrade your jacks to the HappiJac Electric Truck Camper Jack System # LC736514-ELKIT. The Manual-to-Electric Conversion Kit for HappiJac Truck Camper Jack Systems # LC733960-182524 is only available for the 4220 and 4820 jacks. There is a strong likelihood the jack would fail if used on a different jack/model.

The reason it will not work for your 4160 is that the 4160 is a 2 piece construction acme screw drive, and the roll pins that connect the acme screw to the upper assembly can shear with the clutchless motors..
