USA Standard Spartan Locker For GM 12 Bolt Car & Truck w/ 30 Spline Axles

Yukon Gear & Axle is well-known for its robust drivetrain components, and their Spartan Locker is a prime example of that commitment. If you're looking to significantly improve traction for off-road adventures or demanding work applications, this locker is designed for GM 12-bolt rear ends with 30-spline axles. It's a mechanical locker that provides a reliable 100% lockup, meaning both rear wheels will always turn together, giving you maximum grip when you need it most.

This lunchbox-style locker is designed to fit inside your existing differential case, simplifying installation compared to a full-case locker. Yukon has updated the design to eliminate the need for thrust washers and uses a unique spring and pin setup that makes installation much easier. This means you can get back on the road or trail with improved traction without a complex installation process. It includes a heavy-duty cross pin shaft for added durability.

This locker fits a wide range of classic GM vehicles, including models like the Chevrolet Impala, Chevrolet C10 Pickup, and GMC C15/C1500 Pickup. It's a solid option for anyone looking to enhance the capability of their vehicle's drivetrain for challenging terrain or heavy towing.
