ATI Torsional Input Shafts

4.91 out of 5 stars 11 Customer Reviews

ATI torsional input shafts work like a torsional spring bar--twisting and returning to totally eliminate breakage, while reducing shock loads to the gear train. They are manufactured from top-quality 300M or Vasco for maximum durability. Available for GM Powerglide or TH400 splines, these ATI torsional input shafts will add some reliability to your drivetrain.
