Perfect rear differential locker for those who are on a budget and for those who are looking for a easy installtion. Powertrax Lockright lockers are hard to beat. Of course, selectable lockers such as ARB air lockers would be much more desirable, the Lockrights get the job done for a fraction of the cost. Many differentials have a set of spider gears which allow the outside tire to turn faster than the inside for a smooth turn. These lockers still allow for this at low torque. But when you add torque or are heading strait down the road the locker automatically delivers 100% lockup to keep you moving.
These have been running strong and have held up for years, and will for years to come. We feel the Lockright is a better product than others on the market and cheaper too.
