A four wheel independent suspension allows each wheel to move up and down independently from the rest of the suspension. This means that all four of the vehicle’s wheels will always be in contact with the ground. This constant ground to wheel contact means that you, as the driver, will have maximum control of the vehicle. If a drive wheel loses contact with the ground, it can’t provide motive force to propel the vehicle down the road. If a “steering” wheel loses contact, you lose directional control over the vehicle. Four wheel independent suspension systems make sure this doesn’t happen.
