Importance of traction
When your vehicle lacks traction
Anyone who drives a car, SUV or light truck over a landslide may have noticed that one wheel will slip before the other. Once this happens, it is difficult for the vehicle to continue uphill, usually one wheel slips. The spinning wheel spins and takes power from the other wheel on the axle. In addition to the inconvenience and annoyance caused by jamming, there are some safety issues to consider, such as possible injury when trying to release the vehicle and increasing the chance of accidents.
Bottom line: greater traction makes an important safety difference in avoiding jams and enjoying better vehicle control while driving.
The traction system is the ideal solution for almost all light trucks, sport utility vehicles and muscle vehicles on the road today. Whether you need to increase the safety of traction in daily commuting, entertainment and work, or just to make your muscle car power the road instead of burning a wheel.
Traction is also important for outdoor enjoyment and entertainment. Whether you want your muscle car to have two stripes when it goes offline, or want your family to go to their favorite ski resort, or prepare for leisure cross-country, hunting or fishing at the weekend, you need traction.
