This is our newly redesigned poly engine mount for the 3800 market. Reduce engine movement and drivetrain loss by eliminating the stock oil filled mount. We have updated the appearance and quality of the mounts vs. our old version. Solid poly with internal mount "skeleton". We have also increased the stud length to accommodate for those running our cradle spacers. Since this is a full poly mount you may notice a slight increase in NVH. 

Fits on any 97+ 3800 W-Body vehicle. 

Does not work on Bonneville, Park Ave, Firebird or any non-WBody car.
