Mine weighs 3800 lbs..... Looking at aluminum heads, thats 40 lbs off. the HS9500i is about 30 lbs lighter than my 8250. Looking for other ideas. Also does anyone know how much a CJ-7 Tub weighs ?? I was thinking around 800-1000, Might have to go tube frame...

Thanks

"BIGMOTOR" Refers to my VERY mild 383 stroker motor... Thinking of 4.3L but i love the TORQUE !!

Hey Daniel, when you bringing that beast to the Hammers:D :D

remove anything that isnt needed. like the rear floor, why not mount toolboxes etc, on tabs welded to the frame instead of the floor.

Come on now man, how much can a piece of 36"x36" sheet metal really weigh:confused: :rolleyes: :confused: If you're gonna start rippin sheet metal, go all the way and tube it;)

Has anyone actually wieghed a rig, then took off the body and tubed it, then wieghed it again? seems like it would be heavier. sheetmetal VS .120 wall tubing I know my tube front fenders wiegh alot more then my stock ones, but they are rollover approved:) just a thought.

Is removing the body on a jeep and replacing it with tubes actually lighter? sheetmetal VS .120 wall tube.........I know my tube front fenders are alot heavier than my stock ones.........but they are rollover approved:) Just a thought?

Maybe you should check out bgreens lightwieght gas cap:flipoff2: J/K

Aluminum Body, from JP offroad.. Ive seen those tubs take more abuse that a regular body can handle.. Watched one at the last competition drag the entire passenger side body down a rock face.. and he came away with scratched stickers... Really impressed me..

uh i hope you dont mean a CJ7 tub weighs 800-1000 LBS:eek: id say like 200 or a little more

there isn't that much more tube than there is in your roll cage to replace what the body does. you just lose the 200lbs. tub and you really lose weight when you go tube frame.:beer:

Weighed it this weekend ,. Came in at 5995 lbs. That's not too bad for all one ton stuff with a big block and a striped s-10 body. When we had the k5 body it weighed in at 7900 lbs. Ouch!

A CJ tub has to weigh more than 200 lbs. 4 of us just about busted a nut carrying around my tub when I had it off the frame.... A cherokee DOOR weighs about 40-50 lbs.

Hey fullsize, I just moved to G.V. from chico. Are you affiliated with J&J or Sierra xtreme?

My rig was 3500 lbs in this photo...

Nearly done with the tubing job. It's only 2500 lbs right now with just a few items missing, steering wheel, plastic fenders, lights, winch rope and seats ...

well im saying a stripped tub, NOTHING but the body. im guessin you still had the rollbar,seats and everything still in it. otherwise if it IS stripped then you are WEAK:flipoff2: me and my dad lifted it out of the pickup and put it in my garage:D (mine was stripped completely, cept for seatbelts ;)

Go with a 302 they are like 100 lbs lighter than a 350 and appox 75lbs heavier than a 4.3 than aluminum heads on a 302 gives you 30lbs heavier than your 4.3 and the TORQUE you love...

the assassin weighs 3300 lbs with 750lbs axles so swap in some D33 and you have a 2300 lbs vehcile.

We weighed a few rigs at the past couple of comps just for fun.... Here are the weights as I remember them from memory:

My Rig: 3615
Chris Durham's rig: 3620
Mike Shaffer's Suzuki: 2550
H8Monday's YJ: 4500 :eek:
Captain America's Jeep: 2950
Currie's Fire Ant: 3400
Mitch Guthrie's FJ40: 3380
Jason Paule's Jeep Buggy: 3850
Shannon Campbell's Buggy: 3400
Welderboy's new buggy: 3800

That's all I can remember right now. Obviously all of these numbers aren't exact, but they are damn close as far as I can remember....

While were are on the topic, what is the weight difference between 22r,4.3, and a zuki motor? Anyone know, because i want to start my next project with one of the above.

Ian-

with out the ciolover's crawling82's new rig was 2,895lbs we figure when done should be under 3000

So you're hoping to only add 200 more pounds with a floor, firewall, seats, steering wheel, winch rope, pedals, gauges, wiring, and any other misc. stuff you might need? And I sure hope that thing is still getting some more tube. I'll believe it when I see it. I think you're gonna be pretty hard pressed to get your rig under 3000 lbs. using your toyota frame.

:flipoff2: he he he :flipoff2:

If you want a light weight rig you might need to change your mind set. No more over building. You are going to have to build from scratch a few things and try them out, if they are too weak then build them again a bit heavier this time. Its all about custom parts, money, and compromises.

If you just want to get light for cheap, ditch all the amenities. No glass, doors, heaters, AC. Get SMALLER TIRES. Ditch the head lights, tail lights, and associated wiring. Get rid of the spare and carry a bunch of patches, plugs, and tube. hack out the fenders, bob the bed, cut the top off, hack up the dash, floor pan, and anything else that the truck doesnt absolutely need.

Think about a smaller aluminum radiator, they are more efficient so you can run a smaller volume of coolant. Get a smaller gas tank. Ditch all the wiring possible. Buy UHMWPE Rope, light weight bucket seats, alum fuel cell, smaller axles, and aluminum t-cases.

:usa:

edit: and don't forget to buy one of my lightweight gas caps. (should save at least a few ounces :D )

I am working a few tricks here. For one my rope is lightweight Master pull rope, it's only 6lbs. Two more side tubes will be added to the cage that's less than 20 lbs. The 1" X 1" .095 wall floor supports are in so all I have to do is cut out the plastic to fit. Lexan is very light so I think these will be only 3 to 5 pounds each. I will have about 8 different panels so figure that's 25 lbs in plastic. A set of fog lights is what about 2 lbs. The battery, computer harness, fuse box and other electrical is allready on board. My seats are 20 lbs each. The gas tank is allready full with 17 gallons of fuel. Parking brake is on board. My steering wheel is not on yet but I tossed out the origional setup and went with an ultra light alum wheel and lightweight shaft. I will save about 40 lbs in my steering setup over what a regular Toyota would have. I have removed evey one of the factory crossmembers and replaced them with tubing. I have also shortened the wheel base to 102" and cut off the back of the frame. The brake and clutch peddles are now installed. Firewall will be 1/4" lexan plastic, very light.

Counting all the parts that I have left to go, I see less then 100 lbs remaining to install. Testing is planned fr two weeks from saturday. I plan to weight it before taking it to johnson valley. I am sure it will be sevral hundred pounds under 3000.

looking good Chris. where did you mount the stock gas tank at ?

I wouldn't make my firewall out of lexan. It is called a firewall for a reason. I also wouldn't make my floor lexan. That will all melt from the exhaust, and if it doesn't melt then your feet will be VERY hot.

run a 2.5l and d30/35 setup w/ 35" tires, nice n light ;)

Just make sure you trim mostly sprung weight, and not unsprung weight.

Don't forget to fill the Powertank with helium.
ARCA violation, but who's to know on the trail....... :D

Chris, Your buggy looks good but I think i still liked it better as
the truck. It was one of the nicest eary 80's Toy around.

It's mounted above the drive shaft between the frame rails.

i was shooting for 1k or a little more on the new buggy, but the way things are going about 1500 lbs. still a feather weight by rock crawler standards. mike

my shit is 5600 w/spare and full tank. One ton axles 400# ea, ORD Doubler, np435, and small block mopar. too much for my 36x12.5's!!

I don't see how it's possible. Maybe I will bring the scales to OK. ;)

Do you have any pics? That sounds way too light....maybe a typo??? Give us the run down on what you are building.
thanks.

bring the scales lance. i think i have it made at 1500.

I will see if mike will let me bring them......

4 37" tires with rims = 400lbs
2 Dana 44 differentials = 550lbs
-----------------------------------------
950 lbs and you still need: motor, tranny, tcase, chassis, springs/coils, steering, gas tank, seat(s), battery, exhaust, etc. etc. Can't wait to see it! :eek:

Yeah but he is running an ATC 70 engine/tranny/ advance adapted to a t-case out of a 2002 artic cat quad,coils out of a honda pilot, two D batteries run in series, 2 liter bottle for a fuel cell, handle bars off of an old banana seat bike, straight fence tube (1/2") for exhaust, reibar for the chassis and plastic garden chairs for the two seats. :flipoff2:

Brawler nobody asked for the specs on your rig. :D :flipoff2:

Ya know, as i was writing that i figured someone would say that.

no dana 44s here, i am trying to keep it ultra light. either it will work great or chuck parts everywhere. but it will be on 37s but brawler is close on his ideas.
so here is what is coming together
750cc inline yamaha 4 cyl [air cooled]5 speed shaft drive
datsun b 210 4 speed tranny coupled to the yamaha shaft output
samuriai t case
samuria axles i know a strech but i am counting on the light weight for them to live. and besides lance, you were one of the main ones that talked me into the 37s. hell if it works, great if not i will start adding bigger shit. i figure i will start at the other end and make it as light as possible. but it sure is hard not adding extra bracing everytime i am building a bracket or mount. o yea i have 14" clearance under the shaved zook axles. damn if they live it will be kick ass. mike

Damn, i was just kidding. I'll bet you end up with 18-2100 lbs even after all that crazy stuff.






Can you hear the roar of that v4?

man don't say that, bad karma. think light for me, i need all the help i can get to get the zook axles to live.

TTT because I weighed my sh!t last night

It came in at 3750

I'm pretty happy :D

Me and my 10 and 12 year old boys picked my body off the

from the look of most people I see on the trail, we could all shave a good 20-30 lbs on ourselves:flipoff2: :beer:

Trail-ready, with 2 guys, tools, spares, cooler, gas, etc, I'm around 6000 lbs. Not getting lighter any time soon; still needs a cage (tubing is on the garage floor), doubler t-case (have aluminum 241 currently), and bigger tires.

Geez porky. Must be no fun to pull your tank arse out of the mud. :D :flipoff2:

I just weighted my zuk last week. Its got toy axles and an exo, etc.. but stock drive train...

http://www.yager.net/zukin/new/dscf0290.jpg


With me sitting on the back for simulated gastank/tool weight
Total2582
rear #1172 45.2%
front #1410 54.7%


Stock zuke axles just wont hold up to large tires, toys are worth extra unsprung weight and less spares to carry. Ive alredy outlined where I can cut weight....

Save weight dump the bias TSLs !
dump the 1/4" plate bumpers !
1/8" may dent/bend but it wont go to far...

Like someone said above gotta rethink your approach... only way you can make it work... my next toy will be a sidekick with no lift just big tires... !

-yag

randall has a pretty good engine weight chart here:

i think 4k is an excellent wieght for a built 4x4...

The weight on a 4.3 is 425 and on the same chart I read that a 350 is 600 lbs....

but of corse you can find a chart that will say 575 but pretty much the same depending on what each composition included..... but it is still 150+ lbs....

Total weigh of a vehicle at
1500 lbs... that would be SWEET.....

all you lightweight guys, i'll give ya a tug when your stuck. um, weight = resistance, but it also = traction.:p
