Your rear differential is the last stop in a spectacular sequence of powerful oscillations, gyrations, and vibrations - all in the pursuit of turning chemical energy into kinetic energy.

This is only possible if the right parts receive the right forces.

It's to this service that engine, transmission, and differential mounts are dedicated - and ECS Tuning engineers some of the best in the world.

The ECS Rear Differential Mount for your S4 is a product of countless hours of research and development, minimizing driveline deflection while maximizing strength.

Features include:

• Tuned polyurethane isolators selected for a firm yet compliant ride
• Precision machined billet 6061-T6 housing for durability and corrosion resistance
• Our poly material is more resistant to water, ozone, and chemicals, maintaining its resiliency and elasticity longer than conventional rubber
• Increased drivetrain rigidity and response
• Long-term testing done on multiple vehicles for real-world qualification
