Red Mustang Motor Mounts

The Red Mustang Motor Mounts from PROTHANE are bolt-on polyurethane engine isolation components engineered for small block Ford applications in 1963–1973 Mustangs and compatible vehicles. These motor mounts solve the common problem of excessive engine movement and vibration transfer to the chassis that stock rubber isolators allow after years of use or performance modifications. Whether you're building a street machine, restoring a classic, or upgrading an aging daily driver, aftermarket polyurethane motor mounts restore chassis rigidity and improve throttle response feel by keeping the engine mounted securely under acceleration.

Constructed with steel brackets and red polyurethane bushings finished in zinc oxide coating for corrosion resistance, these motor mounts significantly reduce deflection compared to worn OEM rubber. Polyurethane's superior durometer and material memory eliminate the compliance that causes engine clatter and driveline slop during gear changes or hard launches. The kit design allows direct bolt-on installation to your existing engine bay, with the steel framework providing structural support while polyurethane absorbs vibration harmonics across the RPM band. This material combination is automotive-industry proven for longevity, maintaining performance characteristics without the degradation that age and heat inflict on factory rubber isolators.

Owners of first and second generation Mustangs—particularly those with higher-displacement or modified small block Ford engines—will notice immediate improvements in engine containment and reduced NVH transmission into the cabin. The zinc oxide coating protects against salt spray and engine bay moisture, critical for longevity in daily-driven restorations or vintage performance vehicles. Installation requires only basic hand tools and approximately one hour per side; no frame modifications or welding are necessary. These mounts are an essential upgrade for any small block Ford application where stock mounts have worn or where performance driving demands tighter engine control.
