Each sticker measures approximately 2 to 3.5 inches, giving you a mix of bold and subtle motifs suitable for identifying equipment and personalizing a shop envionment.

The stickers can help identify tools at a glance, aid in organization, and add a touch of personality to a busy workspace. For shop leaders, this set offers an inexpensive way to boost morale and recognition among crew members.

BFXM Brake Caliper Hanger with Rubber Tips

This brake caliper hanger set by BFXM includes two hangers and four rubber tips, designed to hold calipers safely during service. With a length of about 7.87 inches and a width of 1.8 inches, the tool provides stable support while leaving brake lines and hoses undamaged. The hanger is built with a painted surface and anti-rust treatment, combining durability with a straightforward, sturdy metal structure. A key feature is the rubber tips that cushion contact with suspension components and bodywork, reducing the risk of scratches or gouges during a brake service or rotor replacement.
Transmission and brake work often require dependable supports to prevent accidental movement or kinking of hoses. This tool aims to replace less-safe methods like bungee cords or makeshift hooks, offering a safer alternative that reduces the risk of damage to brake lines and surrounding components. Its load capacity reaches up to 107 lbs, making it suitable for a wide range of vehicle heights and setups commonly encountered in diesel service bays.
Orion Motor Tech 1/2″ Dr Diesel Injector Socket Set

Orion Motor Tech presents a focused 6-piece diesel injector socket set designed to simplify fuel line maintenance. Sizes include 12, 14, 16, 17, 18, and 19 mm, covering common injector line fittings encountered on modern diesel engines. The L-type sockets come with a 1/2″ drive for compatibility with standard ratchets, drills, and extensions, enabling smoother operation in cramped engine bays. The 12-point design enhances grip on various nut shapes, while the extended length helps access hard-to-reach injector lines. This set is a practical addition for diesel technicians who regularly remove and install injector lines during tune-ups, repairs, or part swaps.
Key considerations for selecting this tool include compatibility with your existing socket collection, the drive size, and the set’s coverage of injector fittings for your typical diesel vehicles. The durable construction and precision forging contribute to long-term reliability in a workshop environment, where repeated use under torque and heat is common. For techs working on trucks or heavy-duty equipment, this kit supports efficient maintenance with reduced risk of damage to sensitive fuel system components.

They pair well with other shop swag or as a simple personal treat for the team.
