Before looking at the differences between the types of 4x4 it is important to know the function of the 4x4 in general. The aim of the 4x4 is to get more traction when it is hard to find, such as when driving on snow, in muddy terrain or uphill. Roads that are uneven or have surfaces that are not paved also present the opportunity to use our 4x4.
Most 4x4 cars have at least these two "high" and "low" functions that are expressed as 4H and 4L on our activation lever or button. They may also have an "automatic" default setting that is very common in American trucks such as the Ford F-150 and Chevrolet Silverado. Therefore, it is important to know when to use the different settings, as they are required in different scenarios.
As a general rule, the high or 4H setting should be used if our driving exceeds 25km / h on average. However, we should not drive faster than 90km / h in any 4x4 configuration, as this can cause damage to the transfer case, overheating and forcing pinions and crowns more than they should are some of the causes of problems with the transfer.
4x4 Low is generally a more torque setting, meaning a stronger setting to get our inertia car out of demanding terrain, so we will need to use this when trying to build a more secure and robust performance profile.
If we are driving at less than 25km / h and we are trying to get out of a sticky, slippery place, climbing a very steep terrain, going through water, mud, sand, that 4x4 low is the configuration that we will use.
It is extremely important to be attentive to the speed we are going since demanding more a traction configuration is synonymous with problems with the transfer and other components that are not cheap to repair in general.
The differential lock is an extremely important element and that few factory models bring it due to its high cost, as we know, Jeep wrangler led headlights are one of the most popular offroad accessories in the market, the Jeep Wrangler Rubicon brings this system, basically the differential lock allows both wheels to turn at the same time, that is, the differential. does not transfer more movement to the wheel that is with less traction, the blockage by making both wheels of the same axle turn with the same power allows us to get out of very sticky terrain or for example when we are at a flex point where we have a wheel on the air.
There are models that allow you to lock the differentials separately, other models that have a central lock and others that only allow you to lock the rear differential. All this for better performance and off-road experience.
