Lifting the vehicle by raising the suspension alters the propshaft angles, which can cause severe vibration.
Aggressive mud tyres, noisy engine/transmission & the slower speeds associated with hard core off road vehicles usually masks the vibration & drivers often tolerate the additional rattle or drone from propshafts on overrun.
On vehicles lifted around 2" Double Cardan propshafts are usually successful in helping cure the vibrations.
Above 2" a Double Cardan isn't guaranteed to cure the vibration due to the angles involved.
Wide Angled Propshafts are neccessary for vehicles fitted with very long travel suspension where on full axle drop out the original propshaft yoke will bind up straining the joints & ultimately locking the shaft solid, which in extreme cases can literally tear the shaft in half.
