Smart Locking Hubs

Smart Locking hubs are a great way to improve the versatility of your four-wheel drive. If you're looking to have a smoother, more fuel-efficient ride, disengage your locking hub and run your car in two-wheel drive. However, if you find yourself in snow, mud, rain or any other slippery condition, a locking hub can give you the traction you need. Some of our hubs are manually adjusted, whereas others can be operated via a control switch mounted in the cabin.

Locking hubs were initially designed to counter what is known as "transmission wind-up" which occurs when the front and rear (drive) wheels rotate at slightly different speeds, and torque is spread throughout the transmission, thereby damaging it. This would mainly occur on dry or grippy surfaces, and therefore not an issue when the road was slippery. In recent years, the invention of the center viscous differential allows certain cars to run in full-time four-wheel drive by managing how much torque was sent between the front and rear axle
