4WD Low vs 4WD High | What is the Difference? **Heavy Duty Mechanic Explains**

I review my 2022 RAM 2500 and Ram 1500 4WD LOW and explained how 4wd low works, when to use and how to use it properly. I also talk about common 4wd low myths. I explained why 4wd low is the best tool for off-roading in any RAM truck. What is going on today guys! I hope every one is having a good week. I figured I would make a full length video about 4wd low vs 4wd high because I frequently get comments that are simply wrong when it comes to 4wd low. So first I talk about what 4wd low is. In a transfercase you have 2 actions. going from 2wd to 4wd and going from low range to high range. so that leaves us with 2wd high, 2wd low, 4wd high and 4wd low. now most manufacturers won't give you the electronic option to go into 2wd low but it is 100% possible. Now 4wd low or low range simply raises the final drive ratio of the vehicle slowing down the wheel speed but increase the torque in a proportional matter. this is important because this increase in torque is 4wd low is so good off road. This increase in torque gives more control to your wheels allowing for maximum traction in off road situations. There are certain situations where 4wd high may be advantageous like in deep snow or even sand or mud but it would depend on the situation at hand. But general 4wd low is the best option for most off road situations. Jumping into the common myths. 4wd low does not lock up all 4 wheels. if your wheels don't lock up in 4wd high they certainly won't all lock up in 4wd high. 4wd low is all in the transfer case, once power leaves the transfer case and does to your 4x4 differentials. it's up to your diffs to decide how power is split between both wheels. The second common myth is that your front axle locks up. and similarity with the first myth this again is just not true while in 4wd low. the front axle or differential has no bearing on what range the truck is in. if the front diff is going to lock up it will lock in both 4wd high or 4wd lock and 4wd low. anyways guys I hope you liked the video!
