Therefore, we recommend automatic lockers for their reliability and peace of mind: You know it is there and will engage automatically whenever traction is needed. The locker is entirely contained within the differential, so you don't have to worry about air leaks or wiring trouble.

This allows the vehicle to negotiate corners as normal, however in some situations based on load, drag, friction, and steepness of the trail, the locker may remain engaged making it difficult to corner. In the absence of torque, the locker automatically unlocks. When torque is applied, an internal mechanism locks both tires together. This is the most common form of lockers on the trail today.

We offer three types of Locking Differentials: Selectable, Automatic, and Spool. In most applications, Locking Differentials may be installed in front and/or rear, live axle or independent front axles. Locking differentials reduce or eliminate this problem by providing maximum traction to each tire in all conditions regardless of how much traction each tire has. Once this happens, all torque is sent to the lose tire since it now has very low resistance, and thus forward progress is lost. Therefore if one tire experiences less than half the traction of the other, it will receive too much torque and will lose or break it's traction.

Open differentials are useful for city & highway driving, where the road is flat and traction is good, but they are not good for Rock Crawling.įor Rock Crawling, the open differential is undesired because it is only able to divide torque between each tire up to twice the amount of the lowest resistance. We will call this an open differential, and all 4WD trucks are built with one front and one rear differential. Because of this, a device called a differential is used to divide and transmit equal torque to each tire. This is most apparent during cornering where the inside tire travels a shorter distance than the outside tire. In general, the tires on your truck rotate at different speeds.
