Differential Integration and Reinforcement System - reinforce and stabilize your front differential case with the DIRS-F! 100% satisfaction guaranteed.


- Part one, the support arm attaches to the vehicle frame at the same attachment points as the front differential.
- Part two attaches to the differential on the case where the passenger side output shaft side case extension bolts to the main differential case (an area suspect to damage on high-HP modified-engine vehicles).
- Part two then attaches to the support arm and carries an OEM differential bushing to add a third, triangulated integration point to "attach" to and stabilize the differential.


NOTE: The design of the DIRS-F incorporates a pressed in extension for the rear frame mount that is also welded in for strength. There will be inconsistencies in the anodization coating in this area of the brace.

    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.
