I'm new here but here's my issue. I took an 84 Silverado C20 full frame off custom build converted to 4X4 custom 14 bolt front Axel 632 big block, when in two wheel drive and nailed to the floor it twist up the rear drive shaft, first time it ripped out the carrier bearing, upped to a 5" single piece aluminum shaft that shredded the first time I hammered on it. Need a shaft that will hold up.

 

Great to hear from you Airezenmaster! Welcome
