Yep, they’re longer.
I’m just gonna use some steel flat stock.
Put that between the jack and the mount, with it sticking up above the mounts a few inches.
Drill new holes in the desired locations and you’re good to go.
I’ll paint the steel, or if I really get excited I’ll drop it off at the powder coating place.
I haven’t decided if I’ll just use a small separate piece for the lower bracket on the rear corners or if I’ll run one long piece that reaches all the way down there.
I think I’ll try a small separate one and if it seems like it needs it, I’ll do a long one-piece adapter.
I thought about cutting the bolts off the new jack legs and welding them on where I want them, but then I’d have to do that any time I wanted to replace one... which is about every ten times you use a CrappiJac.

consider your self very lucky

this is my first run in with hj all four were just like this ( have many more pix ) less than 1 year old
hj denied any responsibility however Mark Holmes at Bigfoot stepped up and had them replaced when I showed them to him at the factory

I live less than a mile from the pacific ocean and I have never seen rust like that on anything I have let alone my camper jacks. What do you do that allows that to happen? I do see my share of rust but nothing like that.How long were they like that before you noticed?

that camper was a brand new purchase at Coos bay I then went straight to Alaska for 2 full months in Nov, Dec,Jan. returned to NY across Canada I year later the Jack's were like that !!!!!! I live in the foothills of the ADK mts and we get a fairly large number of snow storms BUT this was caused by poor to non existent quality control which is the norm for Crapi Hapi jack, that was then and it appears nothing really has changed, when it concerns quality /quality control they find ways to cheapen mfg costs while charging the end customer more !!!!! Thet were repaired by Bigfoot not Crapi Jack non existent customer support
ps I have a pile of worthless Crappies in my cellar left from earlier replacements , 4new spare motors also have many pix of hj I cut apart to examine causes of jams & problems ect

I wonder how long it sat at that coastal town’s dealer lot? Salt water air is horrible on equipment.

What year was that? When 3 of our 2007 jacks lost flakes of paint about a year later, I naively waited until our 2 year camper warranty was almost up. Even though my HJ’s were passed their 1 year warranty, HJ retubed all 3 and all I paid one shipping to them. They told me they had a run of bad prep resulting in failed paint during the time ours were built.

10 years later and still no issues with all 4, paint or mechanical.

it was a new one in 2001 it had just arrived I called them,( crappi jac )several times about their qc of coatings prep and the different type & grade of surface coatings & finishes and the necessary surface prep and they didn't have a clue of what they doing AND didn't respond like they cared at all.
. lippert / drew now owns the company " but" the original owners are still running the plant they didn't care about quality in the past and from reports it looks like they still don't

After reading the info in 54suds link, I think that I would personally stay with the ball screw for the mere reason that I could drop the jacks to the ground without power. The acme sounds like it needs power to do anything to overcome friction.


ACME screw jacks work awesome and do not need power to go up or down. Had one on a custom fabricated motorcycle lift on the back of our previous RV. Worked flawlessly. Going down was easier but raising the lift with the motorcycle on it was not difficult to do manually. I used an old drill brace to keep the noise down when camping.

The fella who built it was the same jack the marina's use to lift boats out of the water (one jack at each of the four corners).
