Engineered in house and tested on our vehicles, these Engine mounts reduce the massive powertrain shake (sometimes mistaken as wheelhop) that is common in the 2006-2011 Z06 LS7. An excellent solution for high horsepower or high performance Corvettes, we've approached these mounts as a complete system to limit unnecessary movement. The soft stock mounts allow power- robbing movement that shakes the car and can break parts.Constructed with 6061 T1 aluminum and anodized for durability, pair these engine mounts with our Z06 transmission mount for an unbeatable package. We recommend installing these at the same time you do your other engine work. Increase throttle response and reduce power-train shake with this lightweight, well designed package. Our mounts are lighter than stock - every last ounce counts!
