Artec Hardcore Diff Cover for Jeep Wrangler JL M220-D44 Rear

The Artec Hardcore Diff Cover for the Jeep Wrangler JL M220 rear axle armors the factory Dana 44 (M220) rear differential with thick nodular iron. The stock stamped rear cover dents and leaks on a hard rock hit; this cast cover protects the ring and pinion, carrier, and rear locker so your rear diff survives the same trail your front does. It's a clean, roughly one-hour bolt-on with no cutting or welding.

Key Features

• Cast from thick-walled, high-strength nodular iron
• Protects the M220 ring gear, carrier, and rear locker from impacts
• Magnetic drain plug pulls metal debris out of the gear oil
• Black powder-coat finish for corrosion and abrasion resistance
• Includes 12 high-strength steel cover bolts
• Bolt-on install in about an hour

Fitment & Compatibility

Fits the Jeep Wrangler JL (2018-present) equipped with the M220 / Dana 44 rear axle, as found on Rubicon and other M220-equipped models; Gladiator JT models sharing the M220 rear use the same cover. Confirm your rear axle is the M220 (220mm) before ordering, since non-Rubicon JLs may use a smaller rear.
