GM part number 11611128 is the factory fuel injector hold down bracket bolt for 2004.5–2016 LLY, LBZ, LMM, LML and LGH 6.6L Duramax engines. Each injector is held in its bore by a hold down bracket, and this bolt clamps the bracket to the cylinder head to keep the injector seated against its copper seal.
