Happijac 733960 Motor kit
This is an electric (CCS) Motor upgrade kit for your Happijac truck camper jacks. A part of their 2019 line of products, this kit includes the new clutchless, current sensing (CCS) motors with a compatible control board and wireless remote. These motors, when paired with the CCS Control Board, will stop operating when you've raised the jacks into the closed position. This feature will stop you from raising the jacks too far and blowing a fuse due to the motor overworking. Must have the new 4220 or 4820 jacks for this kit to work.
