Each HappiJac Camper Jack features attractive 2-inch square tubing that provides significantly more strength than round tubing. The HappiJac Acme Screw Jack can lift 1500 pounds and the HappiJac Ball Screw Jack can lift 1900 pounds. Each HappiJac Camper Jack is powder coated on the inner and outer tubes to protect against rust and improve appearance.
Each HappiJac camper jack uses the same universal Z-bracket mounting system. The strong and secure Z-bracket mounting system can be installed and/or retrofitted on most campers. For dual-wheel pickup trucks, the optional swing-out bracket is easily installed and provides additional clearance needed for easy loading and unloading.
Electric Upgrade Ability
The Acme (4160), Ball-Screw (4560) and Heavy Duty (4800) Acme jacks can easily be upgraded into a wireless remote-controlled electric jack system with the purchase and installation of a HappiJac motor kit (pn 182522) and wiring kit (pn 182524).
