Aluminum or Steel driveshafts ( Pros and Cons )
What do you guys and gals think? I have the option to have my rear driveshaft made out of steel or aluminum.

I'm not a big fan of alluminum, myself, I've never tried one, but I would think the rock chips would eventually eat the thing up and weaken it. Lightweight is nice, but you just can't beat old school.

Well, it's not a truck, but when GM replaced the driveshaft of my dad's 1994 Camaro Z28 (recall; most of the 6-speed cars, his included, shipped with unbalanced driveshafts) they used the 1LE aluminum driveshaft as a standard replacement. Not a single problem with the driveshaft since, and I know it made doing the clutch recently at least that much easier, heh. It's a good 7 years old and it looks perfectly fine to me, no problems with rock chips or anything.

Absolutely not true, any good quality Aluminum drive shaft from a high performance maker will be stronger and lighter.
And if you really want to get crazy go with Carbon Fiber driveline, Better that both. ------------------ 1972 2wd Blazer, 350/700R4/3:73 posi/NOS. Power is nothing without control!

Aluminum would be stronger and lighter, but maybe not as practical. Probably cost more. But the physics are there for it to be stronger. Since it's way lighter it could be made thicker which would actually give it more strength than a steel one. Just my 2 cents
