Upgrading your Bronco's rear differential cover is a great way to make maintenance easier and to get a tougher look. This aFe M220 Dana 44 Advantek differential cover features machined external fins that help improve cooling and stand out from the black finish of the rest of the cover. 

Easier maintenance. Designed to be both a functional and aesthetic upgrade, the cover features a drain magnetic plug and deep reach fill plug to catch any metal particles in your differential fluid, helping to prevent damage to bearings. A calibration plug helps you get the fluid level right whenever servicing the diff. Easy to access drain and fill plugs mean you can service the diff quickly and easily with minimal mess. An oil level sight glass is included and makes checking your diff fluid easy.

Better performance. The cover features built-in external and internal fins that improve heat transfer and cooling. A larger oil capacity also improves performance over a longer duration than the factory fluid capacity can. 

Features & Benefits: 
  • Great look
  • Better performance
  • Easier and faster servicing
  • Less mess
  • Fits the rear Dana M220 axle
  • Includes sight glass and deep reach magnetic fill plug
