Mag-Hytec

About Mag-Hytec

When it comes to protecting the drivetrain of a hard-working truck, few names carry as much weight as Mag-Hytec. The brand's very identity is rooted in engineering innovation: the "MAG" in Mag-Hytec refers to the signature suspended magnet built into every differential cover and transmission pan — a simple but remarkably effective feature that passively captures ferrous metal particles shed by gears and bearings during normal operation. By removing that debris from the lubricating oil before it can circulate through the drivetrain, Mag-Hytec products help extend the life of differentials and transmissions in tow rigs, diesel workhorses, and recreational vehicles alike.

Built from Aerospace-Grade Materials

Every Mag-Hytec product is cast from A356-T6 aerospace-quality aluminum — the same alloy used in aircraft components — then texture powder-coated black and finished with machined cooling fins. Those fins aren't just cosmetic; they function as heat sinks, dissipating thermal energy away from the fluid inside. The result is lower operating temperatures and improved fluid longevity, even under heavy loads or sustained off-road use.

Sealing is handled by ARP 568 O-rings, which in most applications eliminate the need for a traditional gasket or sealant. All mounting hardware is 303 stainless steel for corrosion resistance, and each unit includes an anodized aluminum dipstick so fluid level checks are quick and straightforward.

Differential Covers

Mag-Hytec's differential covers are the brand's flagship product, available for front and rear axles across the most popular full-size truck platforms from Ford, GM/Chevrolet, Dodge/RAM, and Nissan. Increased fluid capacity means lower peak temperatures, while the integrated magnetic drain plug lets you perform routine fluid changes without ever removing the cover — a genuine time-saver for frequent maintenance.

Automatic Transmission Oil Pans

Mag-Hytec's automatic transmission oil pans bring the same engineering philosophy to the gearbox. Deep-sump designs hold significantly more fluid than the factory pan, improving cooling capacity for transmissions under towing or hauling stress. Compatible platforms include the Ford 4R100, GM Allison 1000 Series, and Dodge 47RH, 47RE, 48RE, and 68RE transmissions, among others. Each pan includes a magnetic drain plug and a 1/8" NPT temperature sender port for those who want to monitor transmission temps in real time.

Drain Plugs & Accessories

Completing the Mag-Hytec lineup are purpose-built accessories including engine oil drain plugs, differential drain plugs, and automatic transmission filter extenders. These components carry the same magnetic debris-capture philosophy into everyday fluid service intervals, ensuring that metal particles are caught at the point of drainage rather than allowed to recirculate.

Backed by a Lifetime Limited Warranty

Mag-Hytec stands behind every product with a lifetime limited warranty to the original owner against defects in materials and workmanship, with O-rings covered for five years. For truck owners who expect their equipment to work as hard as they do, that level of confidence in the product speaks volumes.
