There are a very small percentage of vehicles which are not suited for Trac-Grabbers. It is important to make sure that the Trac-Grabber and the strap have sufficient room to make the full rotation without interference from other parts on your vehicle.
It is recommended to put a Trac-Grabber on each of the “drive” wheels. This will insure that whichever wheel the power is applied to will get the benefit of the Trac-Grabber to get you unstuck. Otherwise the wheel without the Trac-Grabber may just spin freely
Under normal circumstances if Trac-Grabbers are used at the first sign of getting stuck (as soon as tires begin to loose traction and spin) and before a vehicle is totally bottomed out, Trac-Grabbers will get you unstuck.
Trac-Grabbers are designed to install easily on vehicles which are already stuck and unlike “mat” products, since they are installed on the wheels, they continue to provide the traction needed to get back to stable terrain.
