_________________________________________________________

The POWERTRAX LOCK-RIGHT Locker is the original locking differential that could be easily installed in existing case assemblies without any special tools or setup equipment. It has been widely used in demanding off-road applications around the world requiring extreme traction output and high-strength. Because the LOCK-RIGHT eliminates wheel spin-up and therefore its 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 POWERTRAX LOCK-RIGHT LOCKER.?

The LOCK-RIGHT has been used in the harshest conditions around the world by hard-core off-roaders, in towing applications, and even United Nation vehicles in rugged terrain.
For traction output, strength and durability, the POWERTRAX LOCK-RIGHT Locker. rivals much more expensive competitive lockers sold only as complete case replacement assemblies. It is a leading product because the LOCK-RIGHT 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 LOCK-RIGHT LOCKER to satisfy their extreme traction requirements for racing, hot-rods and muscle cars.
The LOCK-RIGHT's operation is fully automatic. Designed to send the engine power to the wheels with the most traction, the LOCK-RIGHT will help get you where you want to go. While traveling straight the LOCK-RIGHT will lock the axles together similar to a spool. However, when the wheels need to differentiate in a turn, the LOCK-RIGHT will allow the outside wheel to rotate faster to complete the turn. The internal gears on the LOCK-RIGHT will overrun each other to allow this differentiation.

When operating off-road, the LOCK-RIGHT 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 LOCK-RIGHT will give you the traction you need.

Whats this coupler thing?

Powertrax make?2 different model lockers for the Sierra, one with a coupler and one without a coupler. The coupler replaces the spider gears and can only be used in the rear axles.

This model contains couplers and cannot be used with stock axles in the front, however if you have upgraded to 26 spline chromoly axles you can use this locker in the front.

Please note - These Lockers are only suitable for the 1.3L Diffs
