If you're looking to amp up your ride's traction without breaking the bank, the Spartan Locker from USA Standard Gear is a solid way to go. This isn’t just any locker; it's designed with a unique spring and pin setup that eliminates the need for those pesky thrust washers. Trust me, installation is a breeze—no more wrestling with complicated setups.

  • Perfect fit for GM 8.5-inch axles with 28 splines.
  • Crafted from tough 9310 steel, so you know it’s built to last.
  • Directly replaces the spiders in a standard carrier case, making it a straightforward swap.

Oh, and you’ve got a one-year warranty against manufacturer defects, so you can install it with confidence. This locker is a great way to enhance your vehicle’s performance, especially if you’re planning on hitting some trails or just want better grip on the road.
