For the serious drag racer with big HP and big tires.  We are very excited to partner with AJ Berge of Hemituner Performance to bring the Per4Mance Development DIRS treatment to their new all-billet differential. In addition to the strength advantages of the billet case, the DIRS bushing carrier provides improved stability under acceleration; triangulated rear mounting; additional case support, and improved driving dynamics.

    Protect Against Diff Damage

    With more than 800HP on tap, launching a Dodge SRT Hellcat or Demon places incredible strain on your drivetrain. We developed the Per4mance diff brace to strengthen the differential case and avoid catestrophic damage, while also increasing rear-end bite and positively impacting wheel hop that can cost you those precious tenths.
