Mag-Hytec Differential Covers & Transmission Pans

Mag-Hytec engineers differential covers, transmission pans, and fluids that give hard-working diesel trucks extra lubricant capacity and cooling capacity factory parts don't offer. Every cover is cast from aerospace-grade A356-T6 aluminum and built around the brand's signature suspended magnet, which pulls damaging metal shavings out of the fluid before they cause wear. Cummins, Powerstroke, and Duramax owners who tow, race, or haul hard lean on that extra margin, and CFM Diesel Performance stands behind parts built to keep you winning down the road.

Why Diesel Owners Trust Mag-Hytec

Mag-Hytec casts every differential cover from A356-T6 aerospace-quality aluminum and builds them around a suspended magnet that catches metal debris before it can circulate through the gears, backed by a lifetime limited warranty.

The lineup includes finned differential covers for added cooling surface, deep-capacity transmission pans that increase fluid volume, and Mag-Hytec fluids formulated to pair with both.

CFM Diesel Performance stocks a growing selection of Mag-Hytec covers, pans, and fluids for Cummins, Powerstroke, and Duramax trucks below. Don't see the exact application you need? Contact our team and we'll help track it down.
