Product Description

The BMR MM300R Polyurethane Motor Mount Kit is designed for 2008-2009 Pontiac G8 and 2014-2017 Chevrolet SS performance sedans to replace the soft, hydraulic factory motor mounts with a more robust performance solution. High-durometer polyurethane bushings reduce unwanted engine movement and deflection, resulting in improved throttle response, more efficient power transfer to the drivetrain, and sharper overall vehicle reaction under acceleration or load. The kit's durable construction and red powder-coat finish ensure long-lasting performance even in demanding conditions.

Built from MIG-welded 1/4" steel plate, with 6061 billet aluminum spacers and a complete Grade 10.9 hardware kit included, this motor mount system installs as a bolt-on upgrade using factory mounting points. Adjustable height spacers allow you to lower the engine by 1/4" or 1/2" to gain additional under-hood clearance for larger components such as headers or supercharger/turbo plumbing and can contribute to a slightly lower center of gravity for improved handling. Whether for street use, drag racing, or road course duty, the MM300R is engineered to enhance drivetrain performance and responsiveness without excessive vibration or NVH.
