Correct Radius Arm Angle After a 4 Inch Lift
A taller front lift on a 1973-1979 F-150 or Bronco changes the radius arm angle at the frame, which can bind the arm and affect ride quality. Tuff Country's 20744 relocation brackets drop the radius arm mounting point 4 in. to restore proper geometry.
Key Features
