UCF heavy-duty differential covers are made from carbon steel plate, not cast from iron like some other lower cost products. Both the one piece formed body and bolt flange are laser cut from 1/4" thick steel. The diff covers are then professionally MIG welded in our fabrication shop by our experienced welders. All UCF diff covers ship bare of any finish with a 3/4" NPT fill plug (where applicable) and mounting hardware.
With bullet-proof covers like these you can bash your diffs into rocks indiscriminately. Upgrade to USA made fabricated differential covers today!
