Easy question- 4x4 Blazer curb weight? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

redz 1970 K5 · 01-25-2005, 01:49 PM

Ran a search, surprised not to find any results. I am guessing between 3,500-4,000 lbs, but I know that someone out here knows for sure.

Thanks in advance!

According to the specs on http://COLORADOK5.com/specs.shtml, 3,677#, For some reason, the '69 is listed at 2,947. I'm guessing that is the weight without the top & GM probably soon realized they were all selling with the tops so decided to add that weight in.

I thought someone listed the top weights and they were around 500lbs for a double wall so your still a few hundred pounds short.

Maybe they didn't include the passenger and rear seats as well? The '69 could have been a base model with no additional options (no top, seats, ac, radio,, 6cyl...)?

I don't have the answer but as a point of reference my '84 1/2 ton SWB 2wd pickup weighs about 3800 lbs on two different truck scales, running without a driver, I imagine a 4x4 blazer has got to be packing on another 800 pounds at least, with the top, transfer case, rocker boxes, extra drive axle and big tires.

I weighed mine at a truck scale on my way out camping at 4100 lbs. It was full of camping gear, full tank, and 2 200 lb men. I figure it must weigh in at around 3500 pounds. My Blazer is a 72 350 auto with double wall top.
With the top off it must be around 3300 pounds. It sure seems to go better with the top off!

Old thread but I got my L8T 6.6 liter/6l90e swapped 72 k5 4x4 weighed at an aggregate company scale and they said that it was 5207 lbs with the top on. I do have a bunch of stereo gear in it but it is not 1000lb worth. I would say maybe at max 200 pounds on the stereo. I was kind of disappointed because I have to recalculate the power to weight calculation that I did before my swap. I am trying to make my acceleration meet that of a Trackhawk. Now I am gonna need like 100 more horsepower. The trackhawk weighs 5356lbs. It has 707 hp.

Time to start dropping weight! Maybe that scale was wildly off???

Additional info.
6l90-245lbs vs Th350-125lbs
L8T-650lbs vs SBC350- 575lbs
Net tank 304 stainless 28.67gal. Vs old tank steel 20 gal

FWIW, I weighed mine when I first built it. it tipped the scales at 4850 lbs without the hardtop. I did have the softopper on.

When I lived in NY, the registration weight that they based their fees from had the weight listed as 4250 for my 1970 Blazer 350 4 speed.
