Product Details

The TeraFlex Dana 44 AdvanTEK HD Differential Cover Kit line is a heavy-duty replacement diff cover (differential cover) for Dana 44 AdvanTEK axles. It is built to take the rocks, debris and other trail hazards that can damage a stock axle cover. TeraFlex designed these covers to reinforce the axle housing and protect the gears inside.

Key Features:

  • Cast from high-strength ductile iron, the same material TeraFlex uses for its HD axle housings, with a thick 3/8-inch wall for added rigidity
  • Designed specifically for the newer Dana AdvanTEK axles
  • Large-diameter fill tube and inspection port at the top, sized for a funnel or gear oil bottle spout
  • Fluid level port that also works as a mid-height inspection port
  • Red TeraFlex logo
  • Black powder-coated finish for corrosion resistance
  • Installation hardware included with the kit

TeraFlex backs the line with the quality and off-road experience it is known for. The kit installs with common hand tools. A gear oil change is part of the job, and the factory gasket is replaced with silicone sealant.
