Engine mounts hold your engine in place and help reduce engine vibration and noise. Factory engine mounts typically include rubber between metal plates for a greater dampening effect, but can be prone to cracking or tearing over time. They also allow more engine movement, which may be fine for stock engines. However, if you have a modified engine with more horsepower, you should consider upgrading to performance engine mounts. They are usually made of polyurethane for increased strength and durability, and can provide a tighter hold on your engine to prevent engine torquing and movement. This means more energy can be transferred through the drivetrain to the pavement. Check out O'Reilly Auto Parts for performance engine mounts and other related parts.
