85 CJ body tub weight

May 05, 2005 15 Replies

I've been Googling, but have come up empty so far.



Does anyone know the weight of a stock CJ body tub? Or the weight of a typical fiberglass replacement tub?



Thanks for any insight.


my first Google hit :)

Extreme Fiberglass tub = 275lbs Kevlar Tub = 325lbs

I would take a guess that a stock steel tub would be 400+ish??

Good point about the roll bar, but surely "ninety pounds" is a typo?

90 pounds does not sound right for all of that REAL steel, I bet my CJ doors weight more that that.

I'd guess that my repop steel `79 tub is well shy of 400#, since I could lift one end at a time without popping a gut. If forced to bet on it my money would say 300#. Of course, the repop steel is thinner than the OEM sheetmetal was.

Naw, the rollbar weighs only about 30 pounds. It is difficult to judge just how heavy the tub is, since (unlike you) I wasn't lifting the whole thing at once.

275 and 325 pounds. One site puts a steel tub at 300. I would have thought= =20 fiberglass would be a LOT lighter.

Either that or I am a s*it load stronger than I think I am... I could easily pick up my 'glass tub and put it on or off the frame when it was empty. Even after I placed the seats and roll bar inside, 2 of us could move it. My front clip can't weigh in more than 50 lb also.

So, with a 'glass front end, you had to run new electrical grounds, and remount the radiator, yes?

Any other gotchas?

I ran a negative battery cable over to the back of the fuse panel and mounted some electrical clamps there for the ground wires. I ran a dedicated 10 ga ground for each harness piece and terminated all of them at the above ground tap.

For the solenoid ground, I mounted that to the side of the engine block behind the alternator. The dash also got it's own ground.

I soldered the ground tags right onto the outside of the front signal lens sockets and soldered it to the plate inside the rear fixtures.

For the rad, I use an old bed frame and just welded up a couple L shapes and used old rad hose squares as vibration washers. It held for 5 years of heavy off roading and one roll over. I finally twisted up enough last fall to snap the metal side strap on the rad, so welded a 1"x1/8" bar along the outside of the rad like [. That held until last week when I snapped the other side on an off road trip. I am just welding that one up today for the next 4 day trip tomorrow. My Rad will now have heavy brackets on both sides like [=====] . :-)

You have to watch the roll bar height. The floor can be too thick so the hard top might not fit on. The heater was a bit of a pain to fit flush so I use spacers and left it pointing a bit to the passenger side. You cannot see this when looking at it. I think I had to shorten the steering brace by 1/4" or so, no trouble there.

I managed to put 6"x1/4"x4" plate under the floor under the roll bar so the frame mount hits the plate and the seat belt is bolted down to it.

All in all I love the 'glass body! It was worth the work and is so light my CJ7 is downright scary with the acceleration it has. She goes like a scalded cat thanks to some nice sites like

Thanks for the clues on some things I wouldn't have thought of. And you're right, that IS a cool site, isn't it? :)

You are more than welcome. Please feel free to ask if you need more ideas.
