I just got mine done....
170..oh the truck/forums/images/icons/tongue.gif/forums/images/icons/laugh.gif/forums/images/icons/wink.gif
My 79 Jimmy weighed 5600, 2 people, half tank, wheeling goods, 4"lift and 35's.
How does yours weigh 4000??? I want the Willy's to be around 4,000 or just under.
I gotta call BS...unless you have a fiberglass body on that thing. Where did you weigh it? My 81 Jimmy with soft top, gutted tailgate, 14 bolt FF, and 36" TSL's weighed in at 5700 lbs on a government scale. I can't see your truck being 1700 lbs lighter...
Last time I hauled junk to the dumps ...I weighed about 5300. Full tank of gas,Full size spare,and other part's.
G.M. '82 preliminary data book;
Curb-weight *Blazer with gas V-8/4WD, no passangers, as per '82 model year*
- Total: 4314 lbs.
- Front: 2304 lbs.
- Rear: 2010 lbs.
If thats true and it should be, since it's straight out of G.M.'s manual. Nix the top, and intirior should bring it down to 4000 or so. But, then add lift/tires and add-ons, and your back up to over 4500 lbs.
Boy, it sure would be nice to trim some fat from these pigs.

Its lookin like mine weighs in more than I thot. Ill have to get it weighed.
did you take the body off? that is very low weight for a 3/4 ton k5...
my 1/2 ton 'k5' weighs 4310#, and i have removed quite a bit of sheet metal. i used chromoly for the cage and an aluminum gas tank to try and reduce the weight even further...the only thing left i could do is add aluminum block and t-case, maybe remove the windshield and replace with lexan.
Mine came in at 4450 with the 350ci, 1/2 ton gear, 4" lift, 33's, top on and all the tar paper removed. I've added a 100lb bumper since then and swapped the 350 for a 415, might have picked up a little there.
the stock curb weight on my 86 is 4444, but I think that is with the tank empty. Right now its probably around 4600 - 4700 with all the sh** i have in the back.
My '72 weighed in at 4600 when i bought it w/ 8" lift, 39's. But that was b4 the 502 and 1 ton axles.
i would say close to 3 tons for me.
I'm not buying those GM numbers...my truck is pretty basic...no door panels, no dash pad, no carpet, no AC, no emissions(early drivetrain, not that I yank emissions stuff off), 2 core radiator, stock bumpers, 33" tires, stock ralley wheels, half tank gas, spare tire, 350/SM465/NP205, 10bolts. I'm at 5000lbs.
To cut 1000lbs off of that, I'd have to remove the transfercase and transmission, and I would almost bet that wouldn't even cover that difference. 'Course, not many of us have ever checked to make sure the scale is actually correct : )
Maybe those GM numbers are based on 2WD variants?
before or after the dougnut??
Are you refering to the "G.M. data book" quotes?
I agree, numbers sound a bit light to me too, but it's what G.M. printed.
Did they swap to 208s in '82? That could have something to do with the weight difference. Smog heads, and some other weight-saveing items too.
2wd specs are as follows:
total- 3851 (wow!)
Also, just 'cus I got the book open here.
Front - 2450
Rear - 2214
Total - 4664
Yes, I'm referring to the GM numbers. Only speaking for my own truck, I could see how removing the t-case, front driveshaft, and front axle MIGHT reduce 500lbs. (you still gotta have suspension up front, it's gotta weigh at least 100lbs on the 2WD anyways) so maybe a 400 pound weight reduction.
I've never picked up a 208 so I don't know how it compares to the 205, but IMO, the 205 isn't THAT heavy. Sure, I'm not gonna carry it with one hand, but it's not like it weighs 300lbs. Say it weighs a full 100lbs more than the AL case.
I also can't vouch for how much the 235/75R15's weigh over the 33x10.5's on my truck now. Say 25lbs per tire more? Thats way more I'm sure, but still, 100lbs.
Soo..using my rudimentary figures, I come up with 200 less pounds on a stripped K5, stock, compared to mine. That would put me at 4800lbs, still "well" above what GM says they weigh. Removing another 400 pounds would likely require both doors and the tailgate to come off.
I kind of pride myself on having my truck as light as possible, yet keeping full functionality...for GM to say that the truck is overweight by 600 pounds kind of hurts! : )
I'm running an SM465 in mine, and I believe in '82 thats what the "stock" transmission was as well, so no weight savings there if so. Don't have my link to the K5 dealer brochure here, but if I did, I would check it. I have one of those preliminary manuals too, they left out 4wd completely...not sure I'd trust those numbers very much, just like I'm not quite sure scales that can weigh vehicles over 50,000 pounds are calibrated often enough to measure 100lb differences accurately....a car with well documented weight ranges got on the same scale, and came out about exactly what it should have been, 3800 lbs.
So, I won't say the GM numbers are wrong, and I won't say that the scales are wrong, because I have no proof except for the scale weight of my stripped down K5, but apparently, someones numbers are wrong, or GM got real clever on weight reduction in '82, that I missed.
The Knight with the K5 body came in at 6900 lbs. I am going to weigh it with the s-10 body on our first trip out in May. I am really hoping it's about 1000 lbs less. I don't know. We added the one ton frame but stripped the s-10 body. we'll see I guess
Egads call me tubbo LOL
When I had the 1/2 ton stuff under it I weighed 5700lbs
After the swap it went to 6300.
I pass 2 truck scales on my way to work. And at both the weight was the same.
My 73 C20 comes in at 5700, I forget what the Burb was but it was kinda hefty.
Are these Dry weights??? The weight of water/oil/tranny fluid/gear oils add up or maybe the rest of us are just too lazy to scrap all the mud off before going to the scales......
I'd say GM's numbers are way out of whack...I've weighed my truck at three different scales now and it's always been 5700 + or - 100 lbs in the same trim. There is no way my 81 Jimmy is 1400 lbs heavier than a dead stock 82 Blazer.
I agree, Dorian/Rene. G.M.'s specs are a bit light.
But it is straight from the guys that built the thing, you would think it would be acurate, why would they lie?
Maybe it's dry, maybe-not. There isn't enough information given to guess.
In any case.
I think a modified 4wd with a blazer frame, drive-train and something resembling a body would tip the scales at no less than 4500 lbs. min.
