Another thing to be aware of when using extended upper ball joints particularly where using them with FMJ spindles the angle of the ball joint stud to ball joint body increases as things get taller... Under full compression that angle increases further... You can reach the maximum angle & when that happens something has to give.... On Fords that happens at about 1.25" & then the stud on the ball joint fails.... Don't know where that point is on a Mopar.... On Fords the fix is an angle plate between the ball joint & control arm....Mopar ball joints screw into the arm, there's no angle plate option....
