Audi S4 Rear Differential Mounts - Torque Solution - Billet - `10-`17. A direct-fit billet rear differential insert designed for Audi S4 (2010–2017) that reduces differential movement and tightens rear driveline response for drivers who want a more connected feel from their car.

This Torque Solution billet rear differential insert replaces the OEM cushion and works with the factory housing to add stiffness where the rubber mount allows movement. The part is intended to provide a firmer rear differential mounting point, which can improve traction consistency under load, reduce drivetrain lash, and sharpen throttle response during spirited driving or track use. It's a popular upgrade for enthusiasts who want a simple, durable modification without extensive chassis work.

Features

• Billet construction for a stronger mounting solution
• Direct fit for 2010–2017 Audi S4 rear differential
• Reduces differential movement and drivetrain deflection
• Simple installation using existing mounting points
