Poly Transmission Mount

The poly transmission mount from G Force Crossmembers is engineered for drivers and enthusiasts who demand superior engine bay control during aggressive acceleration and hard cornering. This polyurethane and steel hybrid mount replaces the factory rubber isolator on Pontiac G8, Chevy SS, Chevy Camaro, and Chevy Caprice platforms, delivering measurably reduced drivetrain movement while maintaining drivability on public roads. Whether you're building a street performance machine or upgrading a weekend warrior, this transmission mount addresses a critical weak point in the factory suspension geometry that allows excessive play under load.

Polyurethane bushings offer substantially higher durometer hardness than stock rubber, dramatically limiting compliance in the vertical and lateral planes without the noise and harshness penalties of solid mounts. The reinforced steel backing plate and black powder-coated finish resist corrosion and vibration fatigue, ensuring consistent performance across thousands of miles. Unlike soft OEM mounts that flex under boost or hard launches, this design maintains precise throttle response and reduces unwanted parasitic motion that would otherwise transfer to the chassis and suspension arms, directly improving shift quality and power delivery consistency.

LS and LT engine swap builders, turbocharged G8 owners, and Camaro performance enthusiasts will see the most immediate benefit from this upgrade, especially when combined with solid subframe and bushing packages. Installation is bolt-on straightforward—direct replacement for the factory mount with no fabrication required—making it an accessible upgrade for both shop and home garage work. The 4.95 lb component is compact and easy to handle, with dimensions of 7 x 5 x 16 inches, fitting seamlessly into tight engine compartments on these Chevy and Pontiac platforms.
