My 80e swap has begun

Cool i get it. Not to thread jack or anything, but in my case would a 3" steel ds be ok in a 3700lbs truck, 28" tire, 4.11 gears, and the gearing of the 60e? or would the aluminum be a better option?

just have to try and find out, some stock trucks use stock shafts and get away with it, some make it , some don't

just a little update, they recommended a 5" diameter shaft, damn! you have the thickest shaft we've ever handled

he's right...mine didnt make it in my '05 avalanche.

im gonna give it shot, my truck weights about half of an avalanche. i think it will hold up for now.

remember, at your power level, it's not about weight or hp, it's about how fast you turn that shaft and it's critical speed.

So acording to your theory, if someone goes from 3.23 gears, 26" tires 1:1 @ 6800rpm, to 5.33 gears and the same tires...everything else remain the same, he will be snapping the driveshaft ??????

Or is just the longer DS as in AVEs, CC, EC tend do to more flexing at higher rpm?

Have you made some stats of how many RCSB have this problem, compare to the others?
