The Laser Tools 4122 is a 3-piece set (8mm, 10mm, 12mm) of deep-reach sockets featuring integrated universal joints. These swivel sockets are mandatory for modern diesel engines where glow plugs are angled away from the technician or buried beneath common rail components. Each socket includes a rubber insert to grip the plug, ensuring it doesn't fall into the engine tray. For larger engines, view the Laser 5389 3-Piece Set or if a plug has already snapped, you will require the Laser 5205 Removal Set.
