      Superior Rear Axle Protection. Taking Gladiator on regular off-road adventures can inadvertently expose its axle to abuse, which can lead to damage. Prevent this potential issue with the Teraflex Dana 44 AdvanTEK M220 Rear HD Differential Cover Kit. This kit features a differential cover that’s more robust when compared to the factory original. This provides your axle with enough strength to take on more aggressive off-road activities like rock crawling. Moreover, this cover features a large sight plug and a smaller oil fill plug designed to for convenient transmission oil changing when out on the trails.

      High-Strength Build Quality. This rear differential cover is made from high-grade nodular iron using an advanced precision-casting process. This combination of quality materials and high-tech manufacturing techniques produces a 0.375-inch thick differential cover that’s extremely strong and fits precisely onto your axle. Rounding out its construction is a wear-resistant black powder coat finish, offering superior corrosion protection.

      Trouble-Free Install Procedure. This differential cover is designed to install onto your Dana 44 AdvanTEK rear axle using the included mounting hardware. You will need a tube of sealant as your stock diff cover’s gasket is not reused. Installation is completed using just standard hand tools.

      Includes a Limited Lifetime Warranty. This Teraflex differential cover kit includes a limited lifetime warranty against manufacturing defects. Please visit the manufacturer’s website for further details.

      Application. The Teraflex Dana 44 AdvanTEK M220 Rear HD Differential Cover Kit fits all 2020 to 2024 Jeep Gladiator JT models.
