USA Standard Spartan Locker For Model 35 w/ 27 Spline Axles and a 1.625in Carrier

The Yukon Gear & Axle Spartan Locker is built around a heavy-duty cross pin shaft, replacing the standard spider gears within your differential case. This lunchbox-style locker is designed to give you dependable, 100% lockup traction when you need it most, and it does so at a cost that makes sense for serious off-roaders and work vehicles. It fits into a Dana Model 35 differential with 27 spline axles and a 1.625-inch carrier bore, a common setup in many Jeep and American Motors vehicles from the late 60s through the early 2000s.

What sets the Spartan Locker apart is its straightforward installation and robust design. It cleverly avoids the need for thrust washers, and its unique spring and pin system simplifies the assembly process considerably. This means you can get reliable, full-time traction without the complex setup or high cost often associated with other locking differentials. It's a well-built unit that provides a significant improvement in off-road capability or when dealing with slippery conditions.

This locker is a solid option for vehicles like the Jeep Cherokee (XJ), Jeep Wrangler (YJ/TJ), and American Motors Eagle, among many others. When you're looking to maximize your vehicle's ability to get through tough terrain or challenging weather, the Spartan Locker offers a practical and effective solution for consistent, full-time traction.
