aluminum drive shaft and torque tube

[roverman]

Stronger than you might think. 3.5" od x 55" long x .125" wall was tested by Action Machine to 44k ft. lbs of torque !  I'm buying the tubing to upgrade my Vette C5  driveshaft to 3.0"  dia. and approx 12" longer, for Hemi Healey. I will possibly splice/lengthen torque tube like amount.  Onward, roverman.

Yep. I used to install aluminum prop shafts on heavy trucks. Some were composite wrapped.

Junkyard Aerostar van aluminum drivelines are popular swap in newer Mustangs. Think I mentioned to Jim Blackwood for IRS halfshafts.

Clan, I really like this C5 design for light weight,  rubber couplers at each end, and the beam and torsion strength, it will add, to the Healey. The new material is $1/inch, but sure beats $850 for a standard length, larger dia. Found a place in Pomoma that  can upgrade the shaft and lengthen the torque tube-yea ! Onward, roverman.
