All new brace kits include everything needed to do a proper installation including inserts.
Order new inserts and complete hardware replacement kits for all brace products here.
Insert description: inserts are for mid-2016 and newer cars that do not have threaded sections in the cross-member from the factory for either 8mm or 10mm bolts.
Simply guide the insert into the existing slots of the cross-member and position for bolt insertion and tighten to spec with no tools!
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.
