1.Thin Low-Durometer Rubber Shell
Factory engine mounts are manufactured using soft 45 durometer rubber with large fluid-filled voids. The factory mounts are designed to be as soft as possible, and sacrifice performance for comfort.

2.Large Voids in Rubber Damping Medium
The factory mounts feature large fluid-filled voids in the rubber damping medium which make them prone to leakage and collapse.

3.Failure-Prone Aluminum Bases
Factory engine mounts use alumium bases which crack and separate, resulting in complete failure of the mount.

1.Our High-Durometer Rubber
Our Mounts feature 50 durometer (Street) or 80 durometer (Track) rubber with void-free and fluid-free construction to decrease unwanted engine movement and improve mount durability.

2.High Strength Plastic Retaining Ring
Our Mounts utilize a high-strength plastic retaining ring to prevent the mount halves from separating.

3.High Quality Steel Mount Base
Our Engine Mounts are manufactured in an ISO/TS16949 certified facility using OEM production techniques and improved material specifications. Our Engine Mount bases are made from steel, for increased strength and to prevent cracking.
