DIESEL TRUCK EXPERTS STANDING BY

The stock suspension & steering components on your GM 2500HD/3500HD work well enough, however you won't have the clearance for larger wheels and tires, and the steering's strength leaves a lot to be desired in heavy duty applications. Suspension components like shocks, springs, track bars, sway bars and much more help to transform the capability and durability of your GM 6.6L Duramax suspension and properly prepare your awesome truck for heavy-duty tasks such as towing and off-roading. Pair your suspension & steering with our selection of Wheels & Tires. GM Duramax Fitments: 2011, 2012, 2013, 2014, 2015, and 2016 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.
