GM Large Trans Mount

The Energy Suspension GM Large Trans Mount (part 3.1129G) is a polyurethane transmission mounting solution designed specifically for General Motors vehicles. This mount is essential for those looking to enhance their vehicle's performance, particularly in modified and high-performance builds, by effectively controlling engine and transmission movement during acceleration, braking, and cornering.

Constructed from durable polyurethane, this trans mount offers superior resistance to oil degradation and maintains its elasticity across a wide range of temperatures. Unlike factory rubber mounts that can degrade over time, the Energy Suspension mount provides improved durability and performance, making it a reliable choice for high horsepower applications. Its design ensures that vibration frequencies are isolated, protecting both the vehicle's occupants and surrounding components.

This trans mount is particularly beneficial for drivers who engage in aggressive driving or have made modifications to their engine, such as forced induction upgrades. Proper installation of the GM Large Trans Mount restores precise transmission positioning, which is crucial for efficient power transfer and enhanced shift quality, making it an ideal upgrade for performance enthusiasts.
