Mag-Hytec

Premium Drivetrain Protection for Hard-Working Vehicles

Mag-Hytec has built its reputation on a simple yet innovative concept: the signature magnet suspended in the oil within their differential covers. This defining feature gives the brand its name and represents their core engineering philosophy—protecting vital drivetrain components through intelligent design and superior materials. As gears and axle components experience normal wear, they generate fine metal particles that circulate in the lubricant. The suspended magnet passively captures this debris, maintaining fluid integrity and preventing contamination from damaging other components.

All products are cast in A356-T6 aerospace quality aluminum and texture powder coated black with matching cooling fins, delivering both functional advantages and distinctive aesthetics under your vehicle. The machined cooling fins aren't just for show—they act as heat sinks to dissipate thermal energy, keeping lubricant temperatures in check during heavy towing, off-road use, or sustained high-speed driving. This increased cooling capacity, combined with greater fluid volume compared to stock covers, helps extend component life and maintain optimal performance under demanding conditions.

Why Mag-Hytec Differential Covers Stand Out

The brand's differential covers represent a significant upgrade over factory equipment for trucks and SUVs that work hard. Each unit is fitted with ARP 568 O-rings for superior sealing, eliminating the need for messy gaskets or sealant in most applications. The magnetic drain plug simplifies routine maintenance—you can change your gear oil without removing the entire cover, saving time and reducing the chance of gasket failure. An integrated dipstick allows precise fluid level verification, taking the guesswork out of refills.

Constructed with 303 stainless steel hardware and covered by a lifetime limited warranty, these covers are engineered for durability. The thick aluminum casting reinforces the differential housing itself, adding protection against impacts from rocks, debris, or rough terrain. For enthusiasts who demand both performance and appearance, the powder-coated finish and precision-machined fins create a custom look that sets their vehicle apart.

Magnetic Engine Oil Drain Plugs and More

Beyond differential protection, Mag-Hytec manufactures engine oil drain plugs that incorporate the same magnetic filtration technology. These precision-threaded plugs capture ferrous materials from engine oil, providing an additional layer of protection for internal components. The magnetic tip collects wear particles during oil changes, giving you visual feedback about what's happening inside your engine.

Whether you're building a diesel truck for heavy towing, preparing a rig for serious off-road adventures, or simply want superior protection for your daily driver, Mag-Hytec delivers engineered solutions backed by extensive real-world testing. Their products are particularly popular among Ford Super Duty, Ram, and GM diesel truck owners who understand that proper fluid management and cooling are essential for longevity when operating under load.
