Bronco Rear Differential Cover


PN: 55060000AA

In stock


The AEV Differential Cover for the 2021+ Ford Bronco is designed specifically for the Dana M220 and offers an added level of protection for your differential when navigating technical terrain. This heavy duty, nodular iron Differential Cover features an axle specific fluid level port, placed at the correct level to meet factory specifications, eliminating the need to guess on oil level or use a dipstick to figure out the correct amount of oil.

For added convenience, the AEV Differential Cover has an oversized oil fill port located on the top of the cover. This fill port not only allows you to easily add fluid in the field if axle repairs are necessary, but also doubles as an inspection port, allowing the user to see inside the differential, inspect ring gear teeth, look for water intrusion or even use a dial indicator to inspect for problems without ever removing the cover.

Please Note: This Differential Cover only fits the Bronco’s M220 rear axle and does not fit Bronco Raptor or Bronco Sport.

Product FAQs

Does this Differential Cover increase oil capacity?

No, we design our Differential Covers to have the same oil capacity as the OEM recommends. In fact, we even include a vehicle specific fluid level indicator plug on the face of each cover. This feature combined with our signature oversized fill plug, make gear oil changes a breeze.

Will this fit a Bronco Sport?

No, this is only for the Bronco (including Sasquatch). This will not fit the Bronco Raptor.

Will this fit a Bronco Raptor?

No, that is the only Bronco model it won’t fit. That variant uses a different rear axle than all the rest.

What is that big plug for?

That is an oversized fill plug, a signature feature on all of AEV's Differential Covers. This not only allows for quick and easy oil changes but also provides access to the ring gear for inspection out in the field.

Does the finish peel or chip easily?

Nope. Our Differential Covers are BOTH e-coated and powder coated for maximum durability and longevity.

What material are these Differential Covers made out of?

All of AEV's Differential Covers are manufactured out of nodular iron for maximum strength and protection.

Where are AEV Differential Covers made?

AEV Differential Covers are proudly made in the fact, they are made right here in Michigan.
