The new Replacement Clutchless Motor Head for HappiJac Truck Camper Jacks # LC759927 are not going to work with your older HappiJac 4150, unfortunately.

Since the correct replacement motors for your system have been discontinued, the only viable solution is for a complete replacement.

I know it's not an ideal situation, however should you be interested in this, I recommend the:

-HappiJac Electric Truck Camper Jack System # LC736514-ELKIT.

This system is going to be the correct replacement upgrade that uses the new clutch-less motors that you mention as well.

This system also has an overall weight capacity of 8,000-lbs, or 2,200-lbs per jack, and has a maximum lift of 34-1/2".
