USA Standard Spartan Locker For Toyota 8in Diff w/ 30 Spline Axles

This USA Standard Spartan Locker is built for Toyota 8-inch differentials with 30-spline axles, commonly found in 4-cylinder models like your 1979-1995 Toyota Pickup or 1984-1995 4Runner. It's a mechanical locker designed to give you 100% lockup, meaning both rear wheels turn at the same speed, all the time. This is a huge advantage when you're off-road and need maximum traction, especially in slippery conditions like mud, snow, or loose dirt.

What sets this locker apart is its robust design and the inclusion of a heavy-duty cross pin shaft. This isn't just a standard locker; it's built to handle the demands of serious off-roading. Because it's a mechanical locker, it engages automatically when you apply throttle and disengages when you turn, so you get that extra grip when you need it without having to flip a switch. It's a popular choice for those looking to significantly improve their vehicle's off-road capability without the complexity or cost of air lockers.

When installing this locker, remember it replaces your existing differential gears. It's designed to fit right into your Toyota 8-inch axle housing. While it's a mechanical locker that works automatically, it's always a good idea to consult the manufacturer's installation guide for specific details and torque specifications to ensure it's set up correctly for optimal performance and longevity.
