BORG WARNER DIFF COVERS AT IR CASTINGS

The BorgWarner brand is one of the most common differentials used in hot rods, found in early Falcons, many Commodores, and Centuras.

These diffs typically feature a basic octagonal-shaped cover. If you want to dress yours up, Independent Retro Castings offers two styles of aluminium covers: a standard finned replacement and a quick-change lookalike over. Both options are well-priced, starting at $236 for the unpolished finned cover, plus postage.

IR Castings also offers replacement diff covers for a wide variety of popular rear ends, including Ford 8” and 9”, in plain or polished finishes.

It's only fair to share…
