2WD
2WD is the normal transfer case position selected when driving on the street and highway.
2WD Low
2WD Low is an optional low range kit for the NVG 231 transfer case that disconnects the front drive output inside the transfer case offering the slow control of 4WD Low with the turning capabilities of 2WD. This is particularly useful when on tight trails that have limited turning radiuses.
4WD High
4WD High can be selected for all wheel traction at higher speeds (20-45 mph).
4WD Low
4WD Low is selected for slow moving traction and control. This is the gear generally selected for trail driving and rock crawling.
ABS
Anti-Lock Brake System is a factory installed option on many vehicle which uses wheel rotation sensors to provide input to the vehicle computer and a control box. The system is designed to prevent wheel lockup during panic stops and when slowing down on slick surfaces.
Air Down
To lower the air pressure in the tires to improve off-road traction.
Anti Sway Bar
The anti sway bar (commonly referred to as ‘sway bar’) prevents body roll and keeps the vehicle from swaying back and forth at highway speeds, this gives car-like handling characteristics. When off-road the sway bars will reduce articulation unless they are disconnected
Approach Angle
When viewed from the side of the vehicle, this is the angle between the ground an a line running directly to the lowest hanging part on your vehicle (usually the front bumper). This is the maximum angle that a vehicle can climb without hitting the front bumper or other component.
Articulation
Articulation refers to suspension flexibility that allows the vehicle tires to remain in contact with the ground while driving over uneven terrain.
Axle
The completed assembly of differential, shafts, bearings and seals necessary to transfer power from the driveshaft to the wheels.
