Hi-Lift mounted under rear seat (how to)

Well, I finally got tired of having my hi-lift mounted to my hybrid cage. It was easy to get to up there, but I was always worried it would get stolen sooner or later. Also it kinda reminded me of some ricer with the big spoiler mounted on the back of his Honda. I decided to see if I could make it fit under the back seat. I knew of other guys who keep their hi-lift's under there, but every one I've seen is just thrown under the seat and isn't attached to anything. I don't like loose heavy stuff inside the Jeep in case of a wreck or rollover, so I decided to build a mount for it under the back seat. It's a tight fit, but with the baseplate removed from the jack and some maneuvering, it fits perfectly and looks almost factory. It's plenty sturdy and easy to remove the jack if the need arises. Total cost was about $6 and a few hours of my time.

Here's how it looked under the back seat before I started.


I started with a 2" x 9 1/2" piece of flat 3/16" stock.


I used my high dollar metal bender to put some bends in to fit the contour of the floorpan underneath the seat.


I ended up with this.


I had to hammer down the hump in the floor about 1/4" to gain enough clearance for the jack to fit between the seat and the floor. It didn't take much. Then I laid the jack in place and center punched where I planned to drill the holes for the mounting bolts.


Next, I drilled holes in each end of my bracket to mount it to the floor, then drilled two more holes to align with those I had already drilled in the floor. I ran 1/2" x 2-1/2" grade 8 bolts through the center holes in the bracket and welded them in place. My welds came out fugly I guess because I didn't take time to clean up the steel. I'm not proud of how they look, but they'll hold.


With the bracket in place, I drilled two more holes in the floor to install the bolts in the end of the bracket which will hold it in place when the jack is removed.


After cutting the carpet for the bolts to go through, this it what I ended up with. Looks stock except for the two bolts sticking through the carpet.


After mounting the jack, I used 1/2" stainless wing nuts to hold it in place.


The seat sits down and latches just like it always did and you don't even know the jack is under there.

wow thats clean!!!! I think im gonna do this as well, however I will have to relocate my snatch block, winch controler, com-a-long, tree saver and gloves. Does the jack fit under the seat with the foot plate attached?

Nice work! That's definitely how i'm going to do mine. I hate putting free stuff on the outside of my car... :)

That is really cool, I haven't seen anyone mount it under the seat before. I hate the idea of them mounted up high and turning into projectiles.

I also just got the exact same work bench as I see in your pics! I just put it together today ha.

You didn't have to clearance the tunnel at all?

For mine to even lay under the seat and be able to close I had to bang the tunnel down a little.

Nice work! I've had my high lift jack strapped to the front of the back seat for awhile but mounting it underneath looks quick & clean. Thanks for posting up.

In my '89 the jack fit in place without any need to bolt it down.
With the seat locked down, the jack couldn't move on it's own.

Try that first, before you drill the floor.

Great mod though, and very well done.

Looks good. Mine is the 60" so it has to be outside. I saw one guy who made a simple bracket like yours that clamps it to the roof rack, then he drilled the bolts to fit a lock on it.

It would have fit without bolting it down, but I don't trust the seat to stay latched in a hard roll. I'm one of those "what's the worst that could happen" guys and I try to prepare for that.

Slick, I like. I've got baby seats in the back so, it would end up being a lot of work to get to it for me. LOL

I agree, better safe that get your head bashed in by a Hi-Lift Jack!

I've been upside down in an XJ and was glad the jack never made it to the front seat.

I know this is an old thread, but I'd figure I'd throw a new compliment your way. In many years of working on vehicles, I've never seen that before. VERY unique. I'm currently using my under seat for recovery gear, and an amp, as well as jumper cables, quick deflator, and some spare U-joints. I wish I had room for a high-lift under there too!

Thanks. I'm using some of the additional space for recovery gear and storage too. I have my snatch strap, a couple clevices, the factory jack and handle my CB antenna, jumper cables and a roll of TP under there. Still room for more, just haven't decided what all to keep there.

Can you still fold the rear seat down, or will the wing nuts catch on the fabric? Thanks

Yes the seatback is fine. The cushion actually rests mainly on the trans hump, so there is still some clearance between the wingnuts / bolts and the cushion. No problems.
