Hijet models
How do I know which Hijet models have 4hi/4lo? Do they all have it or do some trucks just have regular 4x4?
All these lightweight little trucks are super agile off-road, in mud, snow or slippery conditions. 4WD High is used in low-traction but relatively high-speed such as in a dirt road or snowy paved road. 4WD Low is strictly for slow off-roading.
When in 4Lo, your truck is sending torque to all four wheels, but in the low range. It is also beneficial when you need more power for pulling heavy loads at slower speeds or climbing steep grades. Whereas in 4Hi, your front and rear differentials lock together, creating the ultimate traction as it does not offer the same push of torque as 4Lo. 4Hi is best for getting through a situation, not out of one.
