Well that's the thing, in case of the F-4-750's you can find detailed spec sheets and upfitter info anywhere. For a European that's really inconveniant. Ok so most likely a D70, but isnt the Super60 actually the stronger axle with just a less high rating?
Hello, i feels kinda weird, that there is so little information about these trucks, since afaik they are already beeing sold? For example: There is gonna be a 8000lbs driven front axle - what kind of axle is that? This exceeds the standard Dana super 60 Level right? Also the tare weight of the trucks, a naked 55000 4x4 with a short wheelbase for example, would be an awesome truckbase for an offroad camper, but what is the actual weight? Greetings
Does anyone know if the rear end of the 3500 chassis cab is still this extreme huge piece of metal? The number on the link above: http://www.gmfleetorderguide.com/NASApp/domestic/graytabcontroller.jsp?graytabtype=7&rpoid=36178&vehicleid=12793§ion=oi_def are no longer there, so maybe something changed. I guess with this massive rear end and the solid front end, the Chassis Cab frame is probably as strong as a HMMWV-Frame. The rear axle would probably be stronger than the IRS on the Humvee, which leaves only the front suspension as a weakpoint, so maybe with some front upgrades you could built a narrower offroad vehicle from that beast, that could rival a humvee in strenght....
Awesome to see Chevy back at this class! Also nice to see, that there will be a 4x4 version and also one with a straight front axle. Since Chevy was the first/only one to go IFS on their HD-Trucks, i would not have been surprised, if they kept this concept even in the 4/55000 department. Wondering what kind of chassis this one will have. The aforementioned Ford HD went fully boxed with a massive frame. Thiw could be difficult for commercial upfitters in this weight class, but would set the chevy aside from alle the competition. Because as far as i know, the ford and dodge 4/55000 are NOT fully boxed.
Thank you! Well it looks like (page 97) the basi c-channel frame is 233x58mm, sadly the thickness is not mentioned. The middle Part got a huge reinforcement piece bolted on which is 303x73mm and there is even a number for the thickness, which is a quite impressive 7.6mm. Well i'm not a big fan of this frame doubling, a straight c-profile of 303x73x7.6mm for the entire truck would have been at least as strong and much less prone to rust.
Hello! First: I know there is a special forum about these trucks here: http://3500hd.com/index.php?PHPSESSID=eveglrq6b84n3e6r947fqsvhq2& But it seems like you need to wait a quite long time until the admin reacts to a registration and even then there are quite few posts from this year so. What i like to know: Does anyone know the width of one of those nice C3500HD? Especially if they got equipped with a dana 70 front driven axle? As far as i know those 4x4 conversions had been quite popular on this truck and since it is a 15000lbs machine, the dana 70 would make sense. As far as i know, all the modern aged bigger trucks like the Kodiak or a Dodge 4500 are supposed to be quite a big larger. Also: Which kind of frame does this truck use? From what i've seen i guess it is an open c front to rear, but what are the dimensions? Are they closer to the modern aged commercial 3500 rear end or the older Kodiaks of the era? Greetings
Hello, i was looking for some technical information about those older HD trucks with the gvw-range of 18-24.000lbs so probably something like the C65-C70. Problem is, all ai found was this website: http://www.oldcarbrochures.org/NA/GM-Trucks-and-Vans/1960_Trucks_and_Vans/1960-Chevrolet-C60-Series-Brochure There seems to be very little information about these trucks compared for example with older Dodge trucks of this size. I am especially interestet in anything comparable to the Dodge W500, so the tare chassis should not be heavier as 7-7500lbs, it has to be a 4x4 and it should have a gas engine. As far as i know GM was offering stronger front axles and bigger engines as Dodge at the time in their 4x4's but how much heavier did they end up with that? Maybe someone got some old Brochures or owns one of those trucks. Greetings
Well as you can see i am collecting Datas about these trucks from each major brand. Why? Because it is very hard to get your hands on one of these trucks over here, so i can not measure for myself and this kind of information is pretty hard to get. Since i am planning to use the truck offroad and it might get pretty tough, the frame is a very important part and as you can see, it differs more than one would expect it to do in this close competion market. Data about the axles, the transmission and the suspension is much easier to get and most of those parts are quite easy to upgrade, but you're not allowed to tuch the frame. Of course you can not just compare the outer measurements, as i described above, the entire design is important. From the sheere numbers the Chassis Cap frame is much stronger, but since i have no picture of the part where the rear and front frame is combined, it's hard to tell what#s really going on. If the hydrformed front part is exactly the same the entire frame is not really stronger offroad, because it will twist at the front then and if the thickness is generatet by using 2 layers, it is not as strong as one solid piece of metal. In case of the F-550 the boxed front part is also much stronger as the front part of the lighter trucks, so ford designed an entirely stronger frame, but this is of course a class 5 truck, so it's uncertain weather or not chevy did the same. So since the normale fully boxed frame is already really strong and features those nice pipe-crosmembers, it may be the better way to go. Greetings
Well yeah ok but that's a quite theoretical number, when it comes to offroading bending and torsional stress is quite important and at this point the crossmembers are as important as the main rails. The boxed 2500/3500 frame (i guess it is the same frame there?) has those nice pipe-shaped crossmembers which are weldet trough both the inner and outer metal of the boxed frame, this is the way to go. This method is used by the mercedes g-wagon, the mercedes unimog (some models do have a boxed frame for the military), the Mowag Duro, the MAn Kat and so on etc. But the chassis cab, sadly, is using those pretty simple boltet crossmembers which are shaped like pretty simple sheets of metal, ford and dodge do the same thing with their chassis cabs. Does anyone here own a 3500 chassis cab of the new generation and can take a picture or two where this insame material thickness is? are there layers? Is the height only in the topkick area and how is the boxed front part added to the open c-rear? Greetings
Hello, thank you very much for this quite detailed answer! It is very interesting that compared to that, the Dodge boxed Frame looks pretty weak! Less height (depht in gm's words), little less width and little less material strengh. I guess this height(depht) is measured at the biggest part between the two axles, becaise normally at the end and front point it's much lesser in size. Well the chassis cap is of course pretty different, since i guess it is an open c from the first door to the rear? Sadly i do not have the data from the Dodge 3500, but it is definetly bigger than the Ford f-350 chassis cap, (which is only 195mm in height and 77mm in width, so a little more width but far less height) but how the **** did they rech 12mm thikness??? this has to be some sort of double layer! The only truck i know with this kind of frame is the ford f-550 in the 19500lbs version which has to layers , both the same dimensions (195height, 77mm width) and with 7+8mm thickness adding up to around 13mm. But why using an even bigger c-profile of that insane thickness for a 3500 truck? this frame, if the data is correct, would be strong enough for 19500lbs at the least, if it is not combined with the normal boxed 3500 front end, which would be a weak point conidering the overdimensioning of the rear part... Greetings
Hello, since i've read that GM will use the 2011 boxed HD frame a little while longer i think about getting one and i really like to compare it to some other frames i owned or know about. As far as i know the Dodge HD frame is around 190mm in height, 70 mm in witdh and the metal is 4mm thick. Ford uses a similiar boxed part front but sadly remains using an open c in the rear, which is also 190mm in height and 70mm in withd but of course a lot thicker, around 7.6mm to my knowledge. So how about the silverade HD frame? It looks pretty tough, got some nice slid crosmmembers, which seems to be welded more carefully trough both the inner and outer part of the boxed frame than the ram cross members, but how about the sheere frame height ans especially thickness?? Greetings
