2004.5-2005 GM 2500HD/3500HD 6.6L LLY Duramax Sway Bars

Your factory sway bar may not provide the stability and control required for heavy-duty applications. Our heavy-duty sway bars are engineered to reduce body roll and improve control, especially when towing heavy loads. Upgrade to an aftermarket sway bar from Alligator Performance for enhanced confidence and stability while driving your GM 2500HD/3500HD. Pair your new sway bar with our selection of upgraded Steering Components!  GM Duramax Fitments: 2004, 2005 GM 6.6L Duramax. Submodel Fitments: WT, Custom, LT, LTZ, High Country, 1LT, 2LT, Pro, SLE, SLT, AT4, Denali. Some exceptions apply, please see individual product pages for specific fitments.
