Energy Suspension 3.1129G Large 7.5 CC Transmission Mount for GM

Had a nasty driveline vibration on my 2006 Chevy 2500 Duramax. Turns out my stock mount was in 2 pieces! Good fix and upgrade!

I installed this on my 2002 Chevy Silverado 2500HD Duramax/Allison pickup and it works great. Truck feels like it shifts better after replacing my stock rubber one with this poly mount.

Fit perfect on my 2005 GMC sierra 3500 duramax with the Allison 1000 transmission. Took a while to get it lined up. Dont listen to the idiots on the internet though, the preload plate is required to be installed as well as the mount. Energy suspension notes that in the installation manual as well. Its not specifically listed for the Duramax/Allison application but this is the right mount.

great part

Took all the slop out during shifts, and gear selection. Take out the stock rubber mount!

I bought this open box/used for a discounted price. It arrived looking brand new. The box on the other hand, looked like it was a stunt double for the opening scene of the first Ace Ventura movie. I used this as a replacement for OEM mount on a 1991 suburban 4x4 LS swap. Good fit and looks solid! I hope to drive it soon.

Installed on my 2005 gmc 3500 Dually 4x4 with Allison 1000 transmission. Took me 20 min to install. Very good quality. Took care of my shake on accelerating.

Perfect fit on my 2005 2500HD DURAMAX!
