Here we have a good used and running well complete 6.6 LMM Duramax engine assembly removed from a 2008 GMC 3500hd. This is being sold as a complete engine with all accessories and fuel system but WITHOUT any electrical. This is a good running engine with fresh new glow plugs since they are a common failure point. 60 day warranty covers the long block components only, does not cover any serviceable bolt on items which can be swapped from your core engine that we dont need back.
