Product Description

It is important to choose durable rubber bushings for cars, trucks, and SUVs because salt, oil, and a range of other inherently destructive contaminants known to undercars will eventually destroy your rubber bushings. Not to mention a number of weight and torque forces that compress rubber.
The replacement polyurethane components found in Hyper-Flex products stand up well against contaminants that can destroy rubber and have been designed to last longer and not permanently compress
Our Hyper-Flex material is available in a variety of durometers, depending on the product application it is performance tested and race proven it is used for all Energy Suspension products that demand a high level of performance and durability.
Whether you are modifying, building a brand new vehicle from scratch, or restoring an old one, Energy Suspension's Hyper-Flex performance polyurethane should be the focus of your present and future vehicle plans.
After more than 20 years of innovating, engineering, and developing a wide selection of high quality polyurethane components for the automotive industry, Energy Suspension has qualified as the premier manufacturer of high quality polyurethane products.

Selected User Reviews For Energy Suspension 3.1129G Large 7.5 CC Transmission Mount for GM

With the Duramax and Allison in my 2005 Sierra 4x4, the throttle body fit perfectly
5/5

The 2015 GMC Sierra 3500 Duramax with the Allison 1000 transmission paired perfectly with the wheel. I had to wait a while to line it Though it is not recommended by the idiots on the internet, you will have to install the preload plate Additionally, you can find this in the installer's manual from Energy Suspension. Although this mount is not specifically marketed for use with Duramax/Allison, it should fit just fine.

This is awesome! The transmission was a 4l80e fitted to my 2000 Chevrolet K3500
5/5

The design is great! The pan bolts can be removed without removing the mount, allowing easy access to the pan. It is necessary to remove the factory mount in order to remove the pan.

A Duramax engine from 2002
5/5

It looks 5 times more durable than the OEM, I have replaced 4 OEMs in the truck, all of them broke or rusted, the last one broke into 5 pieces when it came out.

The fit is perfect and it works great! Putting it on my Silverado 2500HD Duramax/Allison pickup in 2002 has been a great experience
5/5

I replaced my rubber one with this poly mounting bracket and feel like my truck shifts better afterward.

Quite nice
5/5

needed to drill holes to install bolts made in the USA but none the worse because it worked for years before being replaced.
