70 Suburban on lwb truck frame - The 1947 - Present Chevrolet & GMC Truck Message Board Network

trusty72 · 05-29-2011, 08:44 PM

ok this may have been covered before but i couldnt find it. I have been told a 72 lwb frame is the same as a suburban frame other than the body mounts. i bought a 70 suburban body and this week i will start putting it on the lwb frame. Other than the frame mounts, are there any surprises i might run into? thanks..

Ive also heard that the rear is different but my no limit engineering gas tank for a 67-72 truck fit fine on my 72 suburban so I don't know exactly what is different.

I think it has to do with the arch over the rear axle. If I remember right the arch is higher on the truck frame then on the burb frame and the rear section is higher i think but I am not 100% sure

I searched this site and found at least ten topics that covered this already. Two of them were very specific and listed exactly what was different between a LWB frame and a Suburban one.

the truck frames are cut off strait in the back, where as on the suburbans the rear bumper bolts directly to the rear frame horns like the front does, and i think the rear body mounts are different as well

trusty72 · 06-01-2011, 09:58 PM

ok thanks

*project 67 sub* · 06-02-2011, 07:28 AM

The only differences that I know of are the two listed. On the suburban, the rear bumpers bolt to the frame rails . And the body mounts are different in the rear, from where a pickup cab would end, back

Beelzeburb · 06-02-2011, 06:44 PM

Yep, those are the differences I found. I searched for something along the lines of "suburban frame lwb truck".

These two seemed the most helpful from that search:
