LEXIVON LX-SSPS9166 Spark Plug Swivel Socket, 9/16-Inch, 3/8-Inch Drive

The 9/16-inch LEXIVON LX-SSPS9166 is a thin-wall spark plug socket with a 3/8-inch drive and 6-inch total length. Its magnetic core helps hold a spark plug during removal and installation. A 360-degree swivel gives the socket room to move in confined areas. It is specified for 2004-and-newer Ford F-150 trucks with 5.4L 3-valve Triton V-8 engines.

Highlights

The swivel joint helps reach spark plugs where a straight socket may be awkward to position, while the thin-wall profile is designed to fit into the plug compartment. The magnetic core retains the plug as it is handled, helping make removal and installation more controlled. A knurled shaft provides a textured grip, and the size is laser-etched for easy identification among other tools.

The socket is made from hardened, heat-treated chrome vanadium steel and has a polished, chrome-plated finish. Those details suit a tool intended for repeated spark plug service, and the smooth exterior is easy to wipe clean after a job. Customer feedback commonly praises the magnetic hold, swivel action, and ease of use in tight spaces. Some buyers have reported durability issues with the magnetic ring, so feedback on that component is mixed.

Practical tips

Use the 9/16-inch socket with a compatible 3/8-inch drive tool, and align the swivel with the available access before turning. Its 6-inch length provides reach into the plug area, while the magnetic core helps keep the plug seated in the socket as it is withdrawn or positioned for installation. The tool is described as compatible with 2004-and-newer Ford F-150 trucks equipped with the 5.4L 3-valve Triton V-8 engine, making that fitment a useful starting point when selecting a spark plug socket.

Getting the most from it

For a spark plug service task, the combination of a thin wall and a 360-degree swivel addresses two practical challenges: fitting into a narrow plug compartment and approaching the plug at an angle. The magnetic core supports handling the plug through the socket, and the knurled shaft gives the hand a textured surface during low-torque work. The product description also identifies it as suitable for use with manual torque tools.

Compared with a standard straight spark plug socket, this design adds swivel movement and magnetic retention for access and plug handling. That makes it especially relevant for the specified F-150 engine application, where working space around the plug can call for a more flexible approach. It also serves DIY vehicle maintenance and professional spark plug work without adding a separate specialized mechanism to the tool setup.

What to clarify

Which vehicles is this socket specified for? It is described as compatible with 2004-and-newer Ford F-150 pickup trucks with a 5.4L 3-valve Triton V-8 engine.

What drive size and reach does it have? The socket has a 3/8-inch drive and a 6-inch total length, with a 9/16-inch opening for the spark plug.

How does the swivel help during service? Its 360-degree movement allows the socket to angle into confined areas, while the thin-wall profile is designed for access to the plug compartment.

Final verdict

For spark plug removal and installation on the specified F-150 engine, the LX-SSPS9166 brings together a 9/16-inch magnetic socket, a thin-wall profile, and a full swivel joint. Its 3/8-inch drive and 6-inch reach make it a focused addition to a tool kit for that service, especially when access and controlled plug handling matter.
