I stay on a farm and travel 20 -40km daily on a rutted (sinkplaat) gravel road. I recently sold our 4x4 d4d Fortuner with 260 000km on the clock and bought the Pajero with 78000km on the clock which I am very happy with, the only problem that I experience with the Pajero is on a rutted road it feels like the vehicle is shaking to pieces

.
I am willing to spend money on a aftermarket suspension to improve the ride but I have no experience with different brands suitable for this particular vehicle, I would appreciate advice in this regard.
