Group A Differential Mount, Escort, Sierra & Sapphire RS Cosworth

Graham Goode Racing Group A Differential Mount – Ford Escort, Sierra & Sapphire RS Cosworth

Developed and manufactured exclusively by Graham Goode Racing, the GGR1071 Group A Differential Mount is a heavy-duty performance upgrade designed to eliminate excessive differential movement and improve drivetrain stability on high-performance Ford Cosworth models.

Originally engineered using proven Group A motorsport principles, this differential mount is built to withstand the increased torque and driveline forces produced by modified and competition engines. Whether you're restoring a genuine RS Cosworth, building a fast road car, or preparing a track or rally vehicle, this mount provides the strength and reliability that standard OE mounts cannot match.

By reducing unwanted differential movement during hard acceleration, gear changes and launch conditions, the GGR1071 helps improve power transfer to the road, delivering more consistent performance while reducing stress on surrounding drivetrain components.

Manufactured to Graham Goode Racing's exacting standards using premium materials, this is a direct replacement for the original differential mount and installs without modification.
