A Chromoly steel driveshaft is highly sought after for its unique properties. Chromoly is a chrome-alloy steel with added carbon content for increased strength, used by many racers in high horsepower applications. But PST doesn’t stop there. Our 3.5-inch Chromoly Steel shaft also comes with 1350 Series “Gold” solid U-joints that are designed for the stresses of drag racing. This PST driveshaft is recommended for dragsters with engine output up to a screaming 3,500 HP.


Every PST driveshaft is manufactured to the industry’s most rigorous standards:
•  Hydraulically straightened tubing built to a .005” total turnout at the center
•  Tube yokes welded to within a .006” runout on each end
•  Computer balanced to less than a ⅛ ounce/inch variance as an assembly
