That I cannot tell you.. Me personally I have no concern. I took some damn rough roads in my truck the other day and went airborne at 90mph and bottomed out my frame. I have thinner .083 wall tubing whereas these im building are .120 wall and mine is still there but its 2wd..

Something I've never really seen addressed with the 80e swaps is the tailshaft height. If you compare to the 60e, the trans mount bolts to the tailshaft more forward on the 60e which I believe leads to elevation of the output shaft compared to the 80 if you mount both on an even plane. Are you accounting for this with your crossmember? The other consideration: how much frame stability does the stock crossmember add. More of a question to ponder but likely insignificant for a street truck.
The crossmember really does look top notch and I'm considering one just for the weight savings alone. My factory xmember was redone by GMracer several years ago and is overbuilt/welded like a tank. I'm guessing it's near 35 lbs.

Considering the trucks already have 6-8 crossmembers from the front to the back of the truck I don't think it'll hurt the stability of the truck. Mine is made of alot thinner metal than these and is around 3-4 lbs.
