The ATC 9996791 Leaf Spring Pin Socket is a heavy-duty, application-specific tool designed for removing and installing leaf spring pins on Mack and Volvo trucks.
Leaf spring pins are critical pivot points within the suspension system, securing the spring eye to the hanger or bracket. These pins are typically:
- High-torque fastened
- Exposed to corrosion, road debris, and load stress
- Difficult to access with standard sockets
The ATC 9996791 is engineered with a specialized socket profile that fits the unique geometry of Mack and Volvo spring pins, allowing for secure engagement and proper torque application.
This tool enables technicians to:
- Break loose seized or high-torque pins
- Apply proper torque during installation
- Avoid rounding or damaging pin heads
Using standard or incorrect sockets often results in:
- Rounded fasteners
- Slipping under load
- Increased service time
- Potential damage to suspension components
The ATC 9996791 provides a tight, positive fit, ensuring maximum contact with the pin and allowing safe use with impact tools or breaker bars.
Constructed from high-strength, impact-rated materials, this socket is built for repeated use in heavy-duty suspension service environments.
