The "legendary" old 3500HD frame -anyone knows the dimensions?

Hendrickson360 · August 8, 2023

Hello!

i guess those beasts will become more and more rare these days, but i would like to know if anyone got the measurements of the boxed front and open C rear for comparision with the more modern day Chassis Caps.

This is the best picture i could find and weirdly enough it looks like this old frame was more like 3 pieces, with a boxed front, a medium sized open c middle and a bigger open c rear.

Maybe someone owns one of those old beauties that in terms of gvw even outclassed its modern day successors?

Kind regards

Take a read here - Document: (gmupfitter.com)

GMT-400 frame details. Not sure if it has thickness and RBM but it should show plenty of other data.

This again ?

Wow this was one wild mix of metal sheets!

No data on the boxed section, but the rear: 223x58x?? for the base, then a huge 288x73x7.6mm extra sheet, going down in size to 190x58x?? + 270x73x7.6.

Weird but definetly strong. I guess compared to that the modern day chassis caps is kinda sortet.

The first year of these trucks (1991) had a problem with frame bending on certain wheelbase models. A reinforcement was added to fix the problem, it's visible below the 'dogleg' at the rear of the cab.
