Steeda Adjustable Motor Mounts for 2005-2014 Mustang directly replace the weak factory hydra bushing engine mounts. While the factory mounts get the damping job done, they can be prone to fatigue and sagging even with only limited hard use. In addition to being much more durable than the factory engine mounts, these engine mounts are adjustable from factory height up to 3/4 of an inch lower to create clearance for superchargers and strut tower braces. Steeda Adjustable Motor Mounts also feature dual durometer bushing packages. Choose the softer red bushings for great control with only minimal increase in engine vibration transmission. Choose the hard black bushings for maximum control, but will increase engine vibration transmission significantly. Black bushings package is highly recommended for competition use only.
