Perfect fit for my '05 Sierra 4x4 with Duramax and Allison.

Fits perfectly on my 2005 GMC Sierra 3500 Duramax with Allison 1000 transmission It took a while to get it right. Don't listen to idiots on the internet, the bias plate needs to be fitted the same way as the bracket. Energy suspension also notes this in the installation instructions. It is not specifically listed for the Duramax/Allison application but it is the correct mount.

Pros
