is the steel thicker in a pick up chassis is it due to the car body offering some rigidity? i.e. I should not EVEN contemplate using a car frame under a 38 pick up leaf sprung with a flathead
35 to 41 ford pick up chassis 35 to 40 ford car chassis is the steel in a pick up frame thicker - rails and inner x
Is a pick-up chassis heavier gauge steel than a car chassis? I don't know, but I cleaned up the question for you
does anyone stamp heavier guage new 35-40 rails stock style to appease the registration gods if not why not!!
why don't you simply search the interweb fool!!! https://www.speedwaymotors.com/Speedway-1935-40-Ford-Steel-Frame-Rails,52422.html what 11 guage in that metric
@nobby I do not know the factual answer to the question. But that does not stand in the way of an opinion. If pickup chassis were, in fact, a heavier gage metal, it can’t be by much or it would have been noticeable and well known after all the decades of Ford devotees who have encyclopedic knowledge of the brand. And that is not the case. So, I say it’s moot. If you have a sturdy passenger car frame.....use it for either a passenger car or pickup build and do not worry about it. edit: I did not see your last post before I replied. I just looked up 11 ga thickness. It is 1/8” or .125”. Given that a millimeter is about .040”, .125” is a skosh more than 3 mm.........by my spurious reasoning. Ray
I believe it’s the same gauge steel used And the chassis doesn’t rely on the car body for help although the body does add something. I think you’ll be fine building your truck unless you’re planning on hauling heavy loads or running faster than 11 seconds with the flat head. Then I’d look for a dump truck or a square tube chassis.
If I remember correctly, Ford frames are same for cars and trucks 35-40. The frame rails and cross members are all the same, only difference was attachment points for the bodies. The rearmost cross members were different in trucks to add support for the bed.
Here is a good source for drawings, when looking at these drawings remember cars and light trucks are the same drawings up to 1940, when a drawing on that site says truck, they refer to greater than 1 Ton vehicles. Vehicles AFTER 1940, cars, light trucks, and 1ton> trucks ALL have different frames. http://www.vanpeltsales.com/FH_web/flathead_drawings_chassis-frame.htm SEE notes A and B in the drawing
They are essentially the same. 41 pickup uses the same chassis, too. I've used them interchangeably across the years. My first 40 pickup used the chassis from a 40 4 door sedan and I didn't have to add any holes to the chassis; just cut off a few car body mounts from the outside of the chassis ahead of the rear wheels. Hope this helps. Al
The 30s era pickup trucks used a car chassis. They did not get heavier until you got into the ton and better trucks. '30s and early '40s fords were just wiggly bastards.
The 1/2T Ford "pickups" were not considered trucks. They are "Commercial Cars" and share the same basic frame with the cars. The main difference is that the 1/2T frame doesn't have the body mounts that a car frame has.
