does anyone know how to tell the difference between a 1 ton and a 3/4 ton frame? i know about the rear springs being 56" on a 1 ton but is there something else you can measure if there are no springs on the frame?

1 ton frame differences
- Thread starter chevyridinhigh79
- Start date
The most obvious difference is in the straight section under the cab - 1/2 & 3/4 ton will be about 8" top to bottom while a 1 ton will be 11".

i measured 6 1/2" and 7" in different spots between the front cab mounts and the rear cab crossmember. i measured my K20 frame and it measured the same and i measured my 1 ton 2wd frame on my rollback and it measured 8". im a little confused still
If it measured more or less the same as the K20 it's not a 1 ton frame, there is a dramatic difference.

im pretty sure i have another 3/4 ton frame then. is there anyplace i can get exact frame measurements? i guess i should have mentioned the frame up for debate is a pickup truck frame and the 1 ton frame i measured is a C30 rollback frame

true 1 ton hase narrow rear spring hangers. thay stick off the frame about 1.5 " not like the 3" stick out on a 1/2 -3/4 ton frame needs.
and the main section is taller longer than 1/2-3/4 ton stuff. i have seen a few now to tell the diffrence by eye sight.
