DIESEL TRUCK EXPERTS STANDING BY

The stock suspension and steering components on your GM 2500HD/3500HD gives your truck a low to the ground stance that isn't suited for off-roading or for fitting larger tires. It's a similar story for your stock steering, which lacks the strength required for heavy-duty applications. Upgrading your suspension with components like shocks, springs, track bars, and sway bars will transform the capability and durability of your GM 6.6L Duramax, preparing your truck for heavy-duty tasks like towing and off-roading with ease. Your new suspension & steering upgrades pair perfectly with our selection of Wheels & Tires. GM Duramax Fitments: 2001, 2002, 2003, and 2004 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.
