This little magnet is a cheap and brilliant trick for engine and gearbox longevity. It's a general-purpose magnet measuring 2.0 inches by 1.25 inches, giving you about 2.50 square inches of magnetic surface area. You stick it inside any fluid reservoir – think oil pans, automatic transmissions, differentials, or gearboxes – onto a flat steel surface. As metal parts wear down inside your engine or transmission, they shed tiny, harmful particles. This magnet acts like a trap, grabbing those ferrous (iron-based) metal shavings and keeping them from circulating and causing more wear. It's designed for internal installation, meaning it lives inside the component, doing its job quietly. A super simple upgrade for any car, truck, or machinery to help catch problems early and extend fluid life.
