LEXIVON 9/16-Inch Spark Plug Swivel Socket — 3/8" Drive, 6" Thin-Wall Magnetic Cr-V Steel

LEXIVON's 9/16-inch swivel spark plug socket is a 6-inch, 3/8"-drive thin-wall magnetic tool built from chrome-vanadium steel for fast, secure spark plug removal and installation in tight engine bays.

Designed for mechanics and serious DIYers, this socket combines a low-profile thin wall, a 360° swivel joint and a built-in magnet so you can reach and retrieve plugs without fumbling or risking drops. The LX-SSPS9166 is especially useful for vehicles with constrained spark plug wells, and is noted for compatibility with 2004 and newer Ford F-150 trucks equipped with the 5.4L 3-valve Triton V8 engines. Finished with a polished chrome plating and laser-etched size marking, the tool resists corrosion and stays serviceable under frequent use.

How does the swivel joint help when access is limited?

The 360-degree ball swivel frees the socket to articulate so you can align the tool even when the torque wrench or ratchet cannot be perfectly straight. That flexibility reduces the need to disassemble surrounding components and shortens the time to remove or install plugs in awkward positions.

• 360° swivel joint provides multi-angle alignment for tight spark plug wells
• 6-inch reach places the socket deep into recessed plug locations
• Works with 3/8" drive torque tools for controlled turning

Why choose a thin-wall magnetic socket instead of a standard socket?

Thin walls let the socket slide into confined plug recesses where standard sockets are too wide, while the internal magnet secures the plug so it doesn't fall into the combustion chamber. This combination speeds up service and protects the plug’s ceramic and terminal during extraction and installation.

• Thin-walled design fits narrow plug compartments
• Internal magnet retains spark plugs during removal and placement
• Knurled shaft gives extra grip when handling by hand

Is the construction durable enough for shop use?

The LX-SSPS9166 is forged and heat-treated from chrome-vanadium (Cr-V) alloy steel for enhanced strength under torque. It receives a mirror chrome plating to resist rust and simplify cleanup after greasy jobs, and the size is laser-etched to stay legible after long-term use.

• Drop-forged, heat-treated Cr-V alloy for reliable turning power
• Polished chrome finish resists corrosion and wipes clean easily
• Laser-etched size marking for quick identification in a crowded toolbox

What vehicles and situations is this socket best suited for?

This socket is a practical choice for many passenger and light-truck engines that have recessed spark plugs, with specific compatibility for 2004+ Ford F-150s with the 5.4L 3-valve Triton V8. It’s optimized for scenarios where reach, plug retention, and socket clearance are required.

• Compatible with Ford F-150 5.4L 3-valve Triton V8 (2004 and newer)
• Well-suited for recessed or hard-to-reach spark plug locations
• Works with manual torque tools and ratchets using a 3/8" drive

Who is this for? The LEXIVON swivel spark plug socket targets home mechanics, backyard restorers and professional technicians who need a dependable, long-reach tool that protects spark plugs during service. If you frequently work on engines with tight plug wells or want a magnetized, thin-walled socket that pairs with 3/8" drive tools and stands up to repeated use, this tool is a practical addition to your kit.
