2021-25 Ford Bronco Dana 44 Rear HD Differential Cover

If you or a buddy has ever peeled the rear diff cover back on a boulder, you already understand the value of real protection. The TeraFlex HD Rear Differential Cover is built from massive 3/8” thick ductile iron to shrug off the kinds of hits that leave lesser covers leaking on the trail.

Designed specifically for the Bronco M220 (Dana 44 Advantek) rear axle, this cover not only protects your gears and seals but also includes a large upper fill/inspection port for easy maintenance and a dedicated fluid level port to fine-tune oil levels—especially handy on lifted rigs with steeper pinion angles. Finished with a durable, high UV–resistant powder coat, this cover is made to take abuse and look good doing it.

Features:

-Dana 44 HD Differential Covers for the new Bronco AdvanTEK axle

-Cast from the same high-strength, 3/8”-thick ductile-iron as all our Tera HD axle housings

-Red TeraFlex logo

-Features a large diameter fill tube/inspection port at the top to accommodate a funnel or gear oil bottle pour spout

-Fluid level port doubles as a mid-height inspection port

-Increases housing rigidity
