aFe POWER Pro Series Rear Differential Cover Black — Part # 46-71350B

The 46-71350B Pro Series Differential Cover from aFe POWER offers serious toughness and style for off-roaders and enthusiasts. Crafted from heavy-duty cast iron, this cover is engineered to protect the Dana M220 rear axle components under harsh conditions. With its sleek black finish, high fill point, and calibration plug preset to the factory fluid level, this cover brings both performance and convenience. Its design reduces rock hang-ups while boosting durability—making it an excellent upgrade for Bronco, Ranger, Jeep, and other compatible models.

Key Features

  • Built from ¼-inch thick cast iron for heavy duty strength.

  • High fill point helps keep the fill plug out of harm’s way on trails.

  • Calibration plug factory-preset to correct fluid level—prevents overfilling.

  • Includes stainless steel mounting hardware for corrosion resistance.

  • Smooth, black coated finish with aFe POWER logo for both aesthetics and reduced snagging on obstacles.

Benefits

  • Dramatically improved protection for the differential housing against trail damage, impacts, and harsh environmental factors.

  • Easier maintenance with the high fill point and calibration plug—less mess, less guesswork.

  • Durable construction means longer service life and fewer replacements or repairs.

  • Aesthetic upgrade that complements rugged builds while still being functional.

  • Backed by a limited lifetime warranty, giving peace of mind for long-term ownership.

Install Difficulty Level
Ease of installation is “moderate.” The cover bolts on in roughly 30 to 45 minutes, depending on experience.
