sharp eyed readers will note that the suburban had 8 lug wheels .
1500 suburbans only came with 6 lug wheels .
so this conversion probably had a conversion to the 2500 front and rear axles .
the 2500 also had a considerably larger rear differential , very large rear Drum brakes in that year . I'm guessing that is about a 1995 to 1996 model .
in any event , nice conversion .
Usually correct, but not always...
You could get a 1500 diesel. It was a de-rated motor and came with the semi-floating 14bolt rear axle (8 lug).
The 2500's diesel and 454gas came with 8 lug and a 14 bolt full-floating rear axle.
The 2500 350gas came with the 8 lug 14 bolt semi-floating axle.
Here's an example of the 1500 diesel... (I had to really look, these are getting hard to find)
1500 Diesel Suburban
I made something similar to BossCamper's hitch..
