Energy Suspension 3.1129G Large 7.5 CC Transmission Mount for GM

Worked great for my modified Duramax.

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.

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.

Bought this mount in January. Has been on for a month now. Notice that it is firmer. Easy to install. Comes with new hardware. Have a trans jack or floor jack and a piece of thick wood to cover the trans pan. Undo the bolts and lift the trans just enough to get the old one out. Install the new one. Lower the trans enough to start the bolts. Drop the trans and tighten the bolts. I bought Merchant Automotive engine mounts. When I install them. I will review those also.

Fit my 2000 Chevrolet k3500 with a 4l80e transmission. Great design! Makes room to take pan bolts off without having to remove the mount. (Factory mount needs to be removed to remove pan).

Fits great, used it to replace my extremely worn out mount on my nv4500 swapped 1986 k30

Perfect quality and was as described properly in the description. I would recommend this product to somebody who is looking for one.

great part

Great quality. Much better than standard rubber mounts

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