USA Standard Spartan Locker For Dana 44 Diff w/ 30 Spline Axles / Incl. Heavy-Duty Cross Pin Shaft

If you're looking to significantly improve traction for off-road adventures or challenging terrain, a locker for your Dana 44 differential is a smart move. This USA Standard Spartan Locker is designed to replace the spider gears in your existing carrier case, offering a robust solution for enhanced grip. It's a popular choice for vehicles like the Chevrolet K10 Suburban, Dodge Ram 1500, and Ford Bronco, among many others, that utilize the Dana 44 axle with 30 spline axles.

What sets the Spartan Locker apart is its compact 'lunchbox' design, which makes installation more straightforward compared to full differential replacements. It features heat-treated 9310 steel internals for added durability and a unique spring-and-pin system that simplifies the assembly process, eliminating the need for thrust washers. This design ensures a 100% lockup, meaning both wheels on the axle turn together, providing maximum traction when you need it most. The fact that the differential doesn't need to be removed from the vehicle for installation can also save on labor costs.

This locker includes a heavy-duty cross pin shaft for added strength. While it offers a significant performance upgrade, it's important to note that this specific model is designed for the standard Dana 44 and does not fit the Dana 44 HD or Jeep JK applications. Always consult your vehicle's specific service manual or a trusted mechanic to confirm fitment and installation procedures.
