If you choosing new car UAZ Hunter or Bukhanka you definitely thinking if you should pay extra for rear differential lock or not. Our advice is: certainly yes, because of many reasons. Vehicle arrives on structurally more modern axles of type Spicer. Differentials are built-in and are quietter and better maintaine (you will save on service) compared to divided axles of type Timken. Riding abillities are on Spicers also better an If you choose additional mountage of the front differential lock in the future it will be much more easier and cheaper. If you hae vehicle only for road travel we still recomend model with rear differential from the factory becasue of reasons writed above.
