We’ve received consistent feedback from customers looking for improved drivetrain control without a noticeable increase in NVH. In response, our engineering team developed a new 60 Durometer Street Density Transmission Mount designed to deliver reduced drivetrain movement while maintaining OEM comfort levels.
The previous 70 Durometer option is now classified as Track Density, intended for applications where maximum stiffness and performance are the priority.
If you purchased the previous 70 durometer variant and are interested in this new softer option, please email techsupport@034motorsport.com.
