We are now able to offer our customers in Australia access to all Happijac products. However the new price list from Happijac together with the high cost of freight from the USA and the current currency exchange rate makes these products a lot more expensive than was previously the case. There is nothing we can do about this at present.  Listed in our store are the main products and we have a list below of all other Happijac products but you will need to contact us for a quote on these items.

There has been a number of changes to the Happijac product range.  Below we have listed some of these changes based on information received from Happijac.  Note that the Happijac website in the USA has not yet been updated with these changes.

Note that in the USA and Canada the jacks that lift and lower slide on truck campers are called JACKS whereas in Australia they are more often referred to as LEGS.  To avoid confusion we have used the term LEG JACKS.

Happijac Leg Jacks

Happijac now offer two sizes in Leg Jacks - the 4220 and the 4820.  The 4220 replaces previous models (4100, 4150, 4160, 4500, 4600, 4560, 4660). The 4220 has the same lift of 34.5" but has the ability to lift 2200lb whereas the 4150 models had a 1500lb lift capacity and the 4500 models had a 1900lb lift capacity. The 4820 replaces the 4800 model and appears to be basically identical to that model with 36.5" of lift and a 2800lb lift capacity.  Both of the new model leg jacks are fully interchangeable with existing Happijac motors and brackets.       Note that the new models are both listed as "Acme Screw Jacks" and it could be possible that they would lift and lower at slightly different speeds than the older models, particularly the 4500 and 4600 models which were "Ball Screw Jacks".

Happijac Leg Jack Motors

Happijac have released a new motor or drive head.  It is a Vertical Orientation Clutchless, Current Sensing (CCS) Drive Head. . This new CCS motor will only work with the new 4220 and 4820 leg jacks and requires a new CCS control board and CCS remote control unit.  The new CCS motors are not designed to work with the older leg jacks like the 4160 and 4800 as they could cause these leg jacks to break or shear roll pins in the leg jacks. The current model Happijac motor (Part No. 182515) is still available,but will eventually be discontinued.

Happijac Control Boards and Remote Controls. 

The existing Control Boards and remote control units have been made obsolete, according to the new price list. However Happijac have a new remote and control board that works with the old model motors (182515). The new Main Logic Board or Control Board (Part 733513) will is compatible with both the current model motors as well as the new CCS motors. The new Wireless Remote Control unit (Part 723915) is also compatible


We ship all Happijac product direct from the USA warehouse.  The prices quoted include delivery to your door.  Delivery takes around 3 weeks.  Note we have no control of shipping and sometimes there are delays. It is cheaper to ship this way as product stocked at our Australian site incurs additional domestic shipping costs.  We can organise shipping in 4 to 5 days but the cost of the parts just about doubles!

Urgent Orders 

We carry some stock on hand, for my Northern Lite customers. We can make this available for immediate shipping but it does incur additional freight (not for Northern Lite owners!).  Generally we keep a small supply of motors, control boards, remotes and some leg jacks.
