USA Standard Spartan Locker For Model 20 Diff w/ 29 Spline Axles / Incl. Heavy-Duty Cross Pin Shaft

This Yukon Gear & Axle Spartan Locker kit includes the locker unit itself and a heavy-duty cross pin shaft. It's designed for Model 20 differentials and specifically for axles with 29 splines. This is a mechanical locker that provides a reliable 100% lockup, meaning both wheels on the axle will turn together under power, giving you consistent traction when you need it most. It's a popular choice for off-road vehicles where maximum grip is essential.

The Spartan Locker is a type of 'lunchbox' locker, which means it's designed to install directly into your existing differential case without needing to remove the entire differential. This design, along with its spring and pin system, makes installation simpler compared to some other locker types. It's built to be a cost-effective way to gain significant traction improvements for a wide range of vehicles. The included heavy-duty cross pin shaft is there to handle the increased stresses that come with a locked differential.

This locker fits a variety of vehicles, including models like the Jeep CJ5, CJ7, and Wagoneer, as well as older American Motors vehicles such as the Javelin and Matador. If you're looking to improve your vehicle's off-road capability or need more consistent traction in challenging conditions, this locker offers a solid solution. It's a well-built component designed to provide dependable performance for your drivetrain.
