    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.
