  • Duramax Shock Buying Guide For Lift Kits

    There are many different shocks available for the Duramax platform and when you factor in different lift kit manufacturers, it can be very difficult to find a shock that will work for your specific application. Below we will help you determine what shocks your application calls for and what will work best on your truck.

    Different Mounting Styles:
    • Before you order your shocks for your lifted truck, verify that the shocks that are currently installed on your truck match the factory style mount (see illustration below).
    • 2001-2010 Duramax Trucks all come with a "stem" mount on the top and an "eyelet" on the bottom of the shock, notice some manufacturers have the shock body on the top and others on the bottom.
    • 2011-2022 2500HD & 3500HD Duramax Trucks all have a "bar & pin" style upper mount and "clevis" bottom mount.
    • Certain lift kit manufacturers change this mounting style when they relocate the shock mounts for various reasons. For example, Rough Country changes the lower "clevis" mount to an "eyelet" mount while keeping the upper mount the factory style "bar & pin" mount. This will require either a custom shock or a direct rough country replacement shock.

    Different Lengths:
    • You will want to measure from the center of the upper mounting point to the center of the lower mounting point (see illustration below).
    • Once you obtain the length of the shocks that are on your truck you can cross reference that information with the lengths listed on the shocks that you are looking for.
