Lifting a Super Duty 4.5 to 6 inches changes the driveshaft angle enough to cause vibration, accelerated wear, and premature failure of factory CV joints. Rough Country's front CV driveshaft corrects that geometry with an extended shaft built specifically for 2017-2022 F-250 and F-350 4WD gas models running in that lift range. Collapsed at 38.25 inches and extended to 39.75 inches, it fills the dimensional gap a lift creates without requiring custom fabrication.
Twice the shaft strength of the factory unit. The Rough Country driveshaft is engineered to handle the added stress that comes with increased operating angles on a lifted truck. Where the stock shaft was designed for an unlocked geometry, this replacement handles the angularity of a 4.5 to 6 inch lift without the fatigue that causes OEM shafts to fail early.
Upgraded CV joints reduce driveline vibration. Better-quality CV joints at each end smooth out the power transfer that factory joints struggle to maintain at steeper angles. The result is a noticeably cleaner idle at highway speed and less drivetrain harshness under load, which matters on a work truck that spends time towing or hauling.
Direct replacement installation. The shaft bolts into the factory mounting locations without modification. With basic hand tools and a lift or jack stands, most installs wrap up in 2 to 3 hours.
