Description

The Spartan Locker from USA Standard Gear is a robust differential locker engineered for Dana 30 axles featuring 27 spline axles. Constructed from durable 9310 steel, this locker is built to withstand demanding conditions and provides a significant strength upgrade over standard components. It functions by replacing the original spider gears within a standard carrier case, converting it into a mechanical locker that delivers a dependable 100% lockup. This kit comes complete with a heavy-duty cross pin shaft, ensuring enhanced durability and performance. The Spartan Locker is designed for a straightforward installation, directly fitting Dana Spicer 30 axles with 27 spline configurations. For specific Jeep JK D30 applications, a compatible case (YC D706008) is required, as the JK case is approximately 0.030" wider. With its 100% lockup capability, the Spartan Locker is an ideal solution for off-road enthusiasts seeking maximum traction in challenging terrains. Its robust construction from 9310 steel guarantees longevity and reliable performance under stress.
