Product Description

The BMR MM300H Polyurethane Motor Mount Kit is designed to replace the factory motor mounts on 2008-2009 Pontiac G8 and 2014-2017 Chevrolet SS vehicles with a performance-oriented solution that reduces unwanted engine movement and deflection. The high-durometer polyurethane bushings provide a firm connection between the engine and chassis, improving throttle response, power transfer, and drivetrain reaction times, while controlling noise and vibration compromise.

Constructed from MIG-welded 1/4" plate steel with durable black hammertone powder coat and equipped with black anodized billet aluminum spacers, the MM300H motor mount kit allows the engine to be lowered by 1/4" or 1/2", offering increased under-hood clearance for larger components and a lower center of gravity for improved handling. This bolt-on kit installs in roughly 2-3 hours and is ideal for street performance, drag racing, or road racing applications where enhanced engine stability and power delivery are desired.
