Energy Suspension 3.1129G Large 7.5 CC Transmission Mount for GM

great part

Works great

Perfect fit on my 2005 2500HD DURAMAX!

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.

No more lose motion from the rotten factor mount putting it in gear.

Amazons fit guide is a little off on this one but this is a perfect fit for my truck. 07 Sierra classic LBZ with the 6 speed Allison.

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.

Better then OEM and last longer
