Hello Ray,

Welcome to etailer, I'm glad you found us =)

Since you're replacing a HappiJac 4150 jack, the correct replacement is the Replacement Jack for HappiJac Truck Camper Jack Systems # LC736515. This is a direct replacement for the 4150 jack, so it is designed to install in place of the original without requiring modifications.

If the jack is still in good working condition and only the motor has failed, you can replace just the motor with the Replacement Clutchless Motor Head for HappiJac Truck Camper Jacks # LC759927. This is also a direct replacement for the original motor head, making it a good option when the jack itself is operating properly but the motor no longer powers or drives it.

What happened to your current jack, wear out over time, or one of those stories that wasn't so funny at the time?
