Lifting a Super Duty diesel changes the driveshaft angle enough to introduce vibration, accelerate U-joint wear, and stress factory CV joints that were never sized for the added angularity. Rough Country's front CV driveshaft corrects that geometry for 2017-2023 F-250 and F-350 Super Duty trucks running 4.5 to 6 inches of suspension lift, replacing the factory shaft with a unit built to handle the new operating angles without complaint.
Proper geometry at lifted ride heights. The shaft measures 36 inches collapsed and 39.5 inches extended, giving it the range of motion needed to track suspension travel accurately at lift heights where the stock shaft runs out of design envelope. Correct driveline angles translate directly to smoother acceleration and less vibration felt through the cab and floor.
Twice the shaft strength of the factory unit. The stock driveshaft was engineered around a stock-height suspension and street-duty loads. Rough Country doubles that shaft strength so the upgraded unit handles the added stress of lifted geometry, heavier tires, and the high torque output of a diesel powertrain without fatiguing prematurely.
Upgraded CV joints included. Better-quality CV joints replace the factory pieces, tolerating the steeper operating angles of a lifted driveline and resisting wear over a longer service interval than the OEM equivalents running outside their intended range.
Product Benefits
- Corrects Driveline Geometry: Engineered specifically for 4.5 to 6 inch lifted Super Duty applications to eliminate vibration from incorrect shaft angles.
- Collapsed Length: 36 inches, providing the correct installed dimension for lifted ride heights.
- Extended Length: 39.5 inches, accommodating full suspension travel without binding.
- Double the Factory Shaft Strength: Handles diesel torque loads and the stress of lifted driveline angles better than the stock unit.
- Upgraded CV Joints: Higher-quality joints tolerate steeper operating angles and last longer than OEM joints running out of their designed range.
- Reduces Driveline Vibration: Restores smooth power delivery from the transfer case forward after a lift installation.
- Bolt-On Installation: Installs in 2 to 3 hours using common hand tools.
Note: Fits 2017-2023 F-250 Super Duty and F-350 Super Duty 4WD diesel models with 4.5 to 6 inches of suspension lift only. Does not fit gas engine models. Does not fit 2WD models.
