Key Features

Built to withstand demanding off-road conditions, the aFe Street Series Dana 44 Diff Cover incorporates several advanced features:

• 3/8-inch thick flange and 3/16-inch thick cover for exceptional structural strength
• Fully TIG welded on both the inside and outside to reinforce all edges and prevent leaks
• Recessed hardware design to minimize snagging on rocks and obstacles during off-road use
• Dual-purpose fill and calibration plug that prevents overfilling of the axle fluid
• Precision-machined aluminum construction for lightweight durability and corrosion resistance
• Compatible with Jeep Wrangler models equipped with Dana 44 rear differentials

Construction & Design

This diff cover is crafted from high-quality aluminum, offering a perfect balance of strength and weight savings. The thick flange and cover material provide enhanced rigidity, reducing the risk of damage from impacts and debris encountered during off-road driving. The fully TIG welded seams on both interior and exterior surfaces ensure a tight, leak-proof seal, enhancing durability and reliability over time.

The machined fins not only add a rugged aesthetic but also help dissipate heat from the differential, contributing to improved thermal management during heavy use. The recessed hardware design protects bolts from catching on obstacles, reducing the chance of damage or loosening while on the trail.
