Reliable Drivetrain Performance

Ensure your drivetrain is operating at peak efficiency with the Hyperco Rear End Locker Spring. Specifically designed for use with Detroit Locker differentials, this spring is a critical component for maintaining proper locker engagement and disengagement. When your differential springs wear out, you may experience inconsistent locking behavior, which can negatively impact your car's traction and handling out of the corners.

Key Features

  • Compatibility: Engineered specifically for Detroit Locker rear-end units.
  • Material: High-grade steel for maximum fatigue resistance.
  • Reliability: Ensures consistent locker engagement cycles.
  • Easy Replacement: Direct fit for standard locker rebuilds.

A properly functioning locker is essential for putting power to the ground in dirt track and drag racing applications. The Hyperco locker spring provides the necessary tension to keep the locker components aligned and ready to engage under load. Over time, these springs can lose their tension due to the extreme heat and stress of racing, leading to "lazy" locker behavior. Replacing them with fresh Hyperco springs is a cost-effective way to restore your differential's performance and ensure that you have the traction you need when it matters most. Don't let a worn-out spring compromise your race day; keep your drivetrain in top shape with high-quality components from GGCRACING.
