E-cowlboy Leaf Spring & Shackle Pin Remover/Installer Socket for Volvo & Mack — 1/2" Drive, Black Oxide Dual-Pin

This purpose-built socket lets technicians and fleet mechanics tackle stubborn, corroded, or seized leaf spring and shackle pins without improvisation. Machined from high-grade steel and finished with a black oxide coating, the tool resists wear and protects against slipping under torque. It matches the two-pin engagement pattern used by Volvo and Mack, making it a direct-fit replacement or upgrade to the OEM 9996791 and TG15103 tools.

How does this socket make removing stubborn leaf spring pins easier?

The socket’s dual-pin design engages the pin recess securely, concentrating torque where it’s needed so the pin turns rather than the socket slipping. High-grade steel construction and a protective black oxide finish let you apply heavy force without premature wear.

• Two-pin engagement aligns with Volvo and Mack threaded pins for positive contact.
• Thick-walled steel resists deformation under high torque.
• Black oxide finish reduces corrosion and glancing slips.

Will this work with my existing tools and drive setup?

Yes — the socket is built for a standard 1/2" drive, so it plugs into common ratchets, breakers, and impact handles used in truck maintenance shops. It replaces OEM part numbers 9996791 and TG15103, so it fits the same pin sizes and engagement geometry used on those applications.

• Compatible with 1/2" drive wrenches, impact guns, and breaker bars.
• Designed to match dimensions of OEM 9996791 / TG15103 alternatives.
• Works on both Volvo and Mack threaded leaf spring and shackle pins.

What build details improve durability and performance?

The socket is forged or machined from premium steel to sustain repeated heavy use in commercial service. The black oxide finish adds a layer of corrosion resistance and reduces glare, while the precise pin pockets prevent rounding and spinning under load.

• High-grade steel construction for long service life.
• Black oxide coating for added corrosion resistance and grip.
• Machined pin recesses to minimize slippage and wear on pins.

Are there any application limits I should know about?

This socket is intended for threaded leaf spring and shackle pin removal and installation on Volvo and Mack suspensions that use the compatible two-pin engagement pattern. It’s not a universal socket for unrelated fasteners; confirm fit with your specific pin diameter and recess before use.

• Best suited for Volvo and Mack leaf spring/shackle applications matching OEM geometry.
• Not intended for non-threaded or non-pin fasteners without matching recesses.
• Use with proper 1/2" drive torque tools and safety procedures.

Who is this for? Fleet managers, fleet service technicians, truck shop owners, and home mechanics who maintain Volvo and Mack heavy trucks will find this E-cowlboy socket useful. It's aimed at anyone needing a reliable, OEM-compatible solution to remove and install threaded leaf spring and shackle pins without resorting to makeshift tools, reducing downtime and the risk of damage to pins and sockets.
