Nissan Patrol سفاري 1985 Manual Gasoline 4WD Manual locking hubs set for Patrol 80-87. Its function is to disconnect the front axles and differential, and the transfer case shaft. This reduces shaking, decreases fuel consumption, and increases the car's responsiveness in the city and on the road. When entering desert or mountainous areas, it is preferable to set the hubs to the LOCK position. When driving on normal roads or when there is no need to use four-wheel drive, set the hubs to the FREE position. Only one set is available. Shipping is available within and outside Saudi Arabia.
