Increase strength and reduce vibration on your 2007-2013 Chevy Silverado or GMC Sierra 1500 equipped with a BDS lift kit by installing auxiliary differential brackets. These auxiliary differential support brackets reinforce the factory rubber mounts that can yield excessive movement when higher torque loads are added with large tires. These support brackets significantly reduce a vibration that can be caused by this movement when running in 4wd at speed. These brackets are specifically designed to fit BDS 4″ and 6″ lift high clearance crossmembers.Additional Attributes:GTIN:00658848619214Installation Time:1 HrProp 65 (C| R or CR):CRProp 65 Short Label:WARNING: Cancer and Reproductive Harm https://www.p65warnings.ca.govProp 65 Warning Label:p65.jpgProp 65 Yes/No:YesPvg Product Status:ActiveExtended Information:Emissions :Emissions Compliance ExemptLife Cycle Status:Available To OrderPackaging:Quantity of Each:1Package UOM:EADimension:11.0000 x 7.0000 x 2.5000 inchesWeight:5.5000 PG
