We offer the best lockers for your 4×4, created to provide 100% traction on demand, without sacrificing any of your vehicle’s highway driving performance. Many people believe that a 4WD and traction go hand in hand, you can’t have one without the other. However, your vehicle’s standard (or open) differential is designed to allow each wheel to turn independently, thus eliminating binding during turns. Off road, this becomes a major burden as engine power will take the path of least resistance, which occurs at the wheels with little or no traction.
