Jack tech

Looking for more ideas for a tire jack.

I currently have a High Lift jack bolted up to the rig but it's heavy, cumbersome and just doesn't work very well. (It's old and abused).

Bottle jacks generally don't have enough travel and anyway, aren't tall enough for my portals.

The King Jack is awesome but cost more than I want to spend.

FOA's race jack is not ready yet.

Maybe a scissor jack and an impact?

What else is out there?

I even thought about making something out of a Fox air shock and a small bottle of co2.

If you decide to go with the King jack then I suggest you don't delay. it is a custom made part and they don't have them in stock.

I was on the phone with them today to get mine hopefully in time for KOH.

2 home brew options that are space savers.

1. air operated bottle jack.

or

2. scissor jack that can be operated with an battery powered impact

What about RADFLO they do a pneumatic jack same as KING I am pretty sure & probably a lot less. It comes in 36" or 48" closed length with 18" height adjustment.
I will find it for you JR

I saw a scissor jack once, was a factory piece from a high end car that slips my mind, had a 12v motor on a scissor jack. Pretty slick, but would have been better with a bigger/quicker motor.

What about a threaded jack? Quick pin for major height adjustment(6" increments or so) and massive allthread turnable by an impact? Like a Bling mobile home jack?

what about those 12 v powered trailer jacks, they stroke out about 18" and are adjustable and light enough... you'd just need a 12 v source. Maybe a quick connect winch plugin somewhere...

I was at the shop yesterday, we hope to have 8-10 jacks to take to KOH. 1 will be given away to the highest placing FOA equipped rig in the LCQ, 1 will be for demo, 1 will go to Off-Road Magazine for a test, and the others....I'll sell them. Current plan is $250ea. Still working out a mounting system......

This is our preproduction jack. It's currently at Benders shop (FU2) for abuse testing. You KNOW the guys there can handle that job!
For those that haven't seen this style jack.... You weld numerous small 1/2"ID pieces of tubing in strategic locations around your chassis/suspension, then the rod sticking out of the side of the jack slides into one of those pieces of tubing to give a secure lifting point to the jack. Stick a cordless 1/2" impact into the top of it and hit the button.....jacks about 18" in about 5 seconds or so.
So far, Bender and crew have used it to break beads, and jack up everything in their shop...including the 4000lb forklift. So far so good....
The production jack will have some small changes as requested by FU2 to make mounting the jack on your rigs easier.

What about starting with something like this ?
or even cheaper, this?
One more here.

Just cut the handel off and weld on a nut for an impact.
Probably could weld some kind of hook to the body.

I seriously thought about using one of these last Saturday for a jack.

If you weld some tubes on the chassis and a solid pin to the jack body like the FOA I think it could work pretty good.

BCC hooked me up with a radflow jack so I didn't get that far into the idea.

The trailer jacks are very slow, even with an impact. Best bet woudl be to have some hi-lift jack mounts on the chassis for easy and no slide support, and have teh hi-lift easily accessible with some form of quick release pin\or quick disconnects.

As much as I dig the hydro\air offerings, would really suck if you are using them at the race and for whatever reason they fail, loose compression, etc....

get your hi-lift lubed up and ready to go

The quality of the gearing in those things usually leaves a lot to be desired...you could probably turn it to powder in no time trying to run it fast with an impact.

We tried it on a trailer jack at my buddy's shop and it worked great - for the first few times. Then it stripped the gears and we had no way to retract it.

Oh...good for you
Nice jack but at $330, it's more then I want to spend.
You see, I blew my entire budget on fire extinguishers for the race pit

Get a scissor jack from a stock vehicle, modify it for quick operation and make an aluminum structure that will allow you to get it lifted high enough to swap the tire? Seems like that would be the cheapest and easiest route. The only thing up in the air is whether it'll lift it high enough or not.

I have a bulldog 7,000 drop leg trailer jack, with a 2" reciever plug welded to the side of it. It slides into a reviever on my trailer toung and I have a spot on my trailer fender where can jack up the trailer with my rig on it. I have picked the back of my tow rig with it, and it worked great. It certainly could be adapted to pickup the axle for sure. Maybe just weld a hook that could go around the axle tube. I would guess that it wont be much lighter than a highlift, but it would surely get it done. If you are going to drive it with an impact wrench I would get a top wind jack. The side wind jacks have lame gears in them and I have broken two sets of gears in mine.

We had one on DSI's rig, it worked but, it also was very limited on what we could do. to get it high enough to lift the axle so we could put a new tire on it, they had added a chunk of steel, but it made it so it could barely get under the axle with a destroyed flat tire. Put it on rough unlevel ground and it was almost impossible.

for mine i did the scissor jack and made 2 different height spacers for 3 heights...flat, flatter, and f-d heights. All fits in an ammo can. Plan on operating it with a ratchet. Just carrying 2 ratchets so one can work on the lugs, while the other mans the jack.

What about taking the concept of the ARB yuppie sand jack (the bag system that runs off your exhaust) and create one that runs off a power tank? Build it narrower and with more lift. I think resque squads and tow companies have something similar, and it would be real light weight (compared to a normal jack) and most seem to carry power tanks anyway. Just a thought

The tow airbags are cool, but spendy.

I like the Baja Designs QwikJack

Quick release= lost in the desert to a new owner. IMO.

For those with front and rear winches, what about using a pulley type mount located by the coilover mounts. hook the rear winch or front winch to them and to rings on top of the axle. Bzzzz Bzzzz and axle is up in the air...

I.e. to repair rear driver's tire. run front winch to front pass side hook and suck down as much as possible. Now run rear winch to rear driver's side enough to lift the rest of the tire.


I think could be done with the right locations and some ingenuity. Similar to what guys with full hydro suspension do lifting tires in the air.

For illustratin purposes (this is an air setup, but similar principle):
