I have been under my 1500 numerous of times and I've worked under my moms 2500 suburban. I have taken measurements of thickness and what not and I found no differences except the fact one is a truck frame and the other has body mounts for the suburban body. It's too costly to have all these different frames made for the weight class. If I'm not mistaken just the drive train, control arms and tbars differ

Nope, you are mistaken.
Upper control arm mounts are in different locations. Unless you're looking at a 2500 "light duty", in which case you are actually looking at a 1500 front frame section.
Lower control arms swap right over between 1500 and 2500. It's how guys get the forged lowers on to a 1500 vice the OEM stamped steel lower arms.
9.25 front diff (IE: 2500) will not bolt into a 1500 without modification. A couple have tired and either had to hack up the diff mounts or added a suspension drop bracket.

Lol okay I was half right. I new part of the control arm differed. But the last part was exactly what I said, the drive train differs from 1500 to 2500

Hmmmm didnt know that the lcas were the same...good to know...but from what i understand since i have an F44 which is a 2500 Light duty basically i already have 2500 bars and springs basically correct?

I promise, no body lift here. I uploaded a blown out one so you can see just how low the frame sits
