What is the GVW ratings for 1.5, 2, and 2.5 tons? I have '53 Chevy that is rated at 16k, a '50's GMC at 19k, and a '52 GMC at 35k.

If I get that right anyway, I can be pretty dense when the DMV is talkin to me, it's usually painful when I go there,... Either way, in my case, we figgured the truck as 8,100x1.5=12,150. The extra 4,050 lbs gives me the 2 ton capacity I'm supposed to have, but again, depends on how the rig is set up & all that. I'm kinda thrown by the old GVW sticker on the side of mine says it's rated to 24K tho,...
I'd go by what your state does to figgure it, if for no other reason than keeping the local yokels off your bumper in the event you actualy mean to haul stuff with them. Other option is to see if there are owners manuals in the online libray that will give you the rated GVW for the year it was built. 1956 GMC 370 dump " 'Tater "1970 VW Volksrod "the Black Bomber" 2007 Chevy Avalanche 2020 Jeep Cherokee Trailhawk, 2005 Harley Davidson FLHTCUI I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans.

A 470 series was a 3 1/2 ton. I sold a '50 GMC 600 series, & it was rated as a 5 ton. | | | | | Joined: Jul 2004 Posts: 5,708 'Bolter | | 'Bolter Joined: Jul 2004 Posts: 5,708 | Wofford,
I not sure what figures you are searching for, but my 1 1/2 ton 4400 has a GVW of 14,000 lbs and a 2 ton has a GVW of 16,000 lbs.
Stuart | | | | | Joined: May 2005 Posts: 41 Wrench Fetcher | | Wrench Fetcher Joined: May 2005 Posts: 41 | I'll have to check the series on the GMC's. The '52 is a tandem axle, but I believe it was converted by a company out of CA. The 2nd axle is just a tag axle, but is set up with regular walking spring suspension. What is really impressive is apparently the conversion co. pulled everything off the frame, sandwiched a 4" wide, 11" tall, 1/4" channel to both outsides of the frame, then redrilled and reassembled the truck. Of course that has to add a good 1000 lbs of weight.
Stuart, your 1.5 ton, is it the same size as a 2 ton, or the smaller 1 ton. Almost everything around here is a 2 ton.
Thanks everyone! More stupid questions to follow!

My rig is a 55/1st 4400 which looks exactly like the two ton rig. I have always used the front wheel dust cover as a clue to GVW. The 2 ton Chevrolet has 5 bolts holding the dust cover on as opposed to the screw on cover on the 1 1/2 ton rig.
Stuart | | | | | Joined: Dec 2002 Posts: 2,549 'Bolter | | 'Bolter Joined: Dec 2002 Posts: 2,549 | Your Tandem sounds like the one I had. I recently sold this 1954 Chevrolet 5400 series COE 16000lb. gvw 2 ton truck, that had a Trucktor Chaindrive Tandem Conversion. The rear tandems were on a separate frame rail that was slid over the factory frame. It went all the way under the cab.

In most states, if you license your vehicle to haul 26,001 or more, you have to abide by DOT road and safety rules. You can actually license your truck for more weight (at least here you can), but you will be required to carry a CDL. This only applies if you're hauling for business and/or profit.
Spanky, Trucktor doesn't ring a bell, but the conversion sounds the same. Did yours have air canisters on the tag axle? And, how did the chaindrive work?

Lookin to get that out of the way around this time next year thru the program at Skagit Valley Coll. I have been eyeballing a smaller trailer and an old tractor with a bucket on it. Could make some chage on weekends clearing & hauling on smaller jobs. The need is there as getting a truck out to your property around here is pretty rough these days with all the construction goin on. Gotta get an engine first tho, one step at a time!  1956 GMC 370 dump " 'Tater "1970 VW Volksrod "the Black Bomber" 2007 Chevy Avalanche 2020 Jeep Cherokee Trailhawk, 2005 Harley Davidson FLHTCUI I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans.

But the same truck with a Taskmaster V8 as the only change was rated at 19,500 GVW and 32,000 GCVW that doesn’t make much sense to me but that is how they where rated. In case you may be wondering GCVW is Gross Combination Weight otherwise the total weight of truck and trailer in combination. One would think if a motor is good to pull 32,000 on a truck and trailer combo it should pull a truck at 19,500 but the manual plainly states same truck different motor. | | | | | Joined: Sep 2006 Posts: 1,276 Shop Shark | | Shop Shark Joined: Sep 2006 Posts: 1,276 | By the way close to 32,000 with the 64 GMC is slow enough with a small block 350 I don't think I would want to try this with a 261 6 in the truck.

It has no series designation on the hood, but the ID plate has it rated at 19,000 GVW. It may have been military. I haven't seen another one with a single axle and 10 bolt wheels front and rear. It has another plate inside the glove box with axle and tranny info (like CLARK trans.) It also has a 302. Did you have reach a certain GVW to get the 302? Terry

The series of your truck should be in the upper left hand corner of this plate. 302's were first used in 1952, on 450-470 series trucks. | | | | | Joined: May 2005 Posts: 41 Wrench Fetcher | | Wrench Fetcher Joined: May 2005 Posts: 41 | Spanky, I checked the plate on the '52 with the 19,000 GVW tag. The number on the ID plate in the glove box, top left corner, says it's a 475. It only has a single axle. You said a 470 series was a 3.5 ton. What the heck is the 475?
