DIESEL TRUCK EXPERTS STANDING BY

The stock suspension and steering components on your GM 2500HD/3500HD perform adequately, but they limit clearance for larger wheels and tires, and the steering strength may fall short in heavy-duty applications. Upgrading suspension components like shocks, springs, track bars, and sway bars can significantly enhance the capability and durability of your GM 6.6L Duramax, preparing your truck for demanding tasks such as towing and off-roading. Pair your suspension & steering with our selection of Wheels & Tires.  GM Duramax Fitments: 2004.5 and 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.
