• Does not require a CARB EO# - emissions compliant

Features

• Replaces the factory stamped steel cover with a durable cast aluminum housing for improved strength and long-term corrosion resistance
• Increased oil capacity over the factory cover for extended gear oil life and better thermal management during towing or off-road use
• Built-in external machined fins increase surface area to transfer heat from the gear oil to the surrounding air for maximum differential cooling
• Magnetic drain plug captures metallic wear particles before they can circulate through the differential and cause premature wear
• Calibration plug preset to factory oil fill level - eliminates the risk of overfilling the differential
• Raw aluminum finish with machined fins for a clean, distinctive under-truck appearance

Product Description

The aFe Street Series Front Differential Cover (46-71100A) is a direct bolt-on upgrade for 2017-2023 Ford F-250 and F-350 Super Duty trucks equipped with the Dana 60 front axle. Replacing the factory stamped steel cover with a cast aluminum housing, it provides a meaningful improvement in both durability and thermal management - two areas where the OE cover falls short during sustained towing, off-road use, or high-ambient-temperature operation. The increased oil capacity over stock extends gear oil life and helps the differential run cooler under load, while the machined external fins accelerate heat dissipation to the surrounding air.

A magnetic drain plug captures metallic wear particles before they recirculate and cause premature gear or bearing wear, and a calibration plug preset to the factory fill level makes refilling simple and accurate. The raw aluminum finish with machined fins delivers a clean, purpose-built look under the truck. All hardware is included for a straightforward bolt-on installation with no modifications required. Compatible with all engines offered in the 2017-2023 F-250 and F-350 4x4 Super Duty lineup.
