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 B7 RS4 is a product of countless hours of research and development, minimizing driveline deflection while maximizing strength.
