@Mehmet Volga Though I do not have a Pajero, I concur with notes from @GauravSoni.
I have had Dobinsons MRA + 2" lift + 50mm spacers (H&R) couple of weeks ago; I could feel the difference in desert. The car is less 'jumpy' and tends to keep you in contact with the sand more.
The above arrangement cost me roughly AED 10K.
There is a promotion going on at Dobinsons now; it may be worth giving them a call.
For the spacers, I checked the reviews for other brands and recommendations on 4x4 groups; do not take chances with these minor stuff when off-roading.
