Enuff background.

What I learned. I'll try to remember what I can.
Application: Offroading or not?
Material choice. Ties into budget & application.
RPM's.

I see your a Z71. Determine if you're gonna go offroading. That'll dictate shaft material. Steel is heavy but may be a better choice here. It wouldn't get easily damaged like if a aluminum shaft collided w/. somethin hittin the trails.
I'm 2wd, so I don't have to worry bout offroading. He said alum. would be better for me.

Then there's carbon. It's strong, but incredibly $$$$.
If this shaft goes beyond its' limits, it disengrates into dust. Bye bye. It's so strong to the point it's brittle like. Cost almost 3x that of alum. for little gain. Very limited amount of pro racers & NASCAR use these.

If I get an alum. shaft, he said I'm lookin at $400 including yokes & u-jts. My truck originally came w/. steel. A new alum. in either 3 1/2" or 4". The 4" obviously is heavier but could spin higher (more RPMs). I'll be goin w/. a 3 1/2" al. more than likely, & hopefully by fall of this yr.

Hope this helped.

You just reminded me, steel balances easier than al. too.

I just checked out that place u listed, they have a lot to pick from.
