A locking differential that can be easily installed without any special tools or setup equipment is ideal for a 4x4 enthusiast. The Spartan Locker now offers a that to those on a budget!
It has been widely used in demanding off-road applications around the world requiring extreme traction output and high-strength. Spartan Lockers eliminate wheel spin-up and therefore the associated driveline trauma is negated, the strength and integrity of its surrounding original case and other driveline components are, in effect, substantially increased. Cases that occasionally fail with open or limited-slip/posi differentials become one of the strongest links in the drive train when equipped with the Spartan Locker.
For traction output, strength and durability, the Spartan Locker rivals much more expensive, competitive lockers sold only as complete case replacement assemblies. It is a leading product because the Spartan delivers as much traction output, its end assembly is exceptionally strong, is much less expensive, and does not require professional installation (because the complete case assembly does not have to be replaced and realigned with precision calibration equipment). An excellent choice for off-road vehicle applications, performance enthusiasts also began using the Spartan Locker to satisfy their extreme traction requirements for racing, hot-rods and muscle cars.
The Spartan's operation is fully automatic. Designed to send power to the wheels with the most traction, the Spartan Locker will help get you where you want to go. While traveling straight the Spartan will lock the axles together similar to a spool. However, when the wheels need to differentiate in a turn, the Spartan locker will allow the outside wheel to rotate faster to complete the turn. The internal gears on the Spartan will overrun each other to allow this differentiation.
When operating off-road, the Spartan Locker will always send the engine power to the wheels that need it most. For example, if you are rock crawling and one wheel is in the air (complete loss of traction), the wheel on the ground will receive the engine power and keep you going. Whether it be snow, sand, mud, ice, etc... the Spartan will give you the traction you need.
Although smoother than other competitive locking differentials, the brute force characteristics of the Spartan Locker limit general application in less tolerant and more mainstream applications. In some vehicles, you will hear a light clicking noise as the gears are overrunning themselves and allowing the wheels to differentiate in a turn. This is normal of most lockers on the market today. We recommend the Spartan for vehicles that are primarily driven in severe driving conditions or are used for recreational off-road. For vehicles that are driven daily or require more mainstream application, the Powertrax No-Slip Traction System offers a quieter and smoother performance.

To assist in identification of your axle by looking at the shape of the differential, we have prepared a differential chart. Please click go to the chart for identifying your axle type.
Note about your carrier: Before beginning to tear down your differential, please be aware that the Spartan Locker is designed to fit open carriers only. It will not install into any type of limited slip carrier.
