Spartan Locker for Dana 30 Differential 27 Spline

The Spartan Locker, manufactured by USA Standard Gear, offers a reliable traction solution at a low cost. Its revolutionary spring and pin design, which eliminates the need for thrust washers, makes installation a breeze. This automatic locker replaces the stock side and pinion gears while utilizing the factory open differential case. The new and stronger center pin fits into oval slots between two inner drivers, and under load, it forces the inner drivers outward to engage the outer axle couplers on each side of the case. This provides locked power to both drive wheels, enhancing traction.

During turning, one driver is unloaded, and the teeth can ratchet across each other, creating differential action to reduce tire wear and make turning the vehicle easier. The Spartan Locker is one of the most economical lockers available on the market today.

The installation process is straightforward, as it simply replaces the spider gears, without requiring any complex differential work. The average installation time is around 4 hours.

Constructed from high-strength 9310 steel, the Spartan Locker is designed for incredible durability and longevity. The heat-treated and precision-cut teeth ensure long-lasting performance.

The Spartan Locker fits the Dana 30 differential, 27 spline. If purchasing this unit for a Non-Rubicon JK front, you will also need to purchase the carrier case part number YC D706008.

In summary, the Spartan Locker from USA Standard Gear provides a cost-effective and reliable traction solution with a user-friendly installation process, high-quality construction, and exceptional performance.
