Aluminum Locker Spring 90# Red

The Winters Aluminum Locker Spring 90# Red is a precision-engineered component designed for serious differential and locker builds in high-performance vehicles. This spring serves as a critical actuator in mechanical locking differentials, controlling engagement and disengagement cycles under load and during turns. Whether you're building a rock crawler, drag vehicle, or dedicated off-road rig, this locker spring ensures reliable clutch pack engagement without unnecessary binding on road surfaces.

Manufactured from lightweight aluminum, this spring with a 90 lbs spring rate offers the ideal balance between actuation force and responsive unlocking behavior. The red finish provides corrosion resistance in harsh environments, extending service life in mud, salt, and extreme weather conditions. At just 0.18 pounds, the minimal weight footprint reduces rotational inertia within the differential carrier while maintaining the structural integrity needed for sustained high-torque applications.

This locker spring is essential for enthusiasts upgrading to electronic or manual locking differentials in Dana 60, Dana 70, or comparable axle housings. Installation requires careful timing and preload setup during differential assembly—proper spring tuning directly impacts performance. With its reliable design, this spring is a must-have for anyone looking to enhance their vehicle's differential capabilities.
