Torque Solution 16-24 Audi A4/S4 (B9/B9.5) Billet Lower Differential Mount Insert

This product includes a billet aluminum insert designed to fit into the factory lower differential mount on your 2016-2024 Audi A4 or S4 (B9/B9.5 chassis). It's made from solid aluminum, which helps to stiffen up the rear differential under load.

When you're accelerating or braking hard, the factory rubber mount can allow for some unwanted movement in the differential. This insert fills in the voids in the stock mount, reducing that flex. This can lead to a more direct feel from the drivetrain, especially during aggressive driving. It's a straightforward modification that doesn't require replacing the entire mount.
