Front Shocks


2011-2017 Duramax 2" Lift NX2 Shock Absorber (BDS85758)-Shocks-BDS-BDS85758-Dirty Diesel Customs

NX2 Series Dual Shocks (4x)

The full hoop design works with the factory axle shock mount and locates the dual shocks to the backside of the coil spring, mimicking the factory shock location. The hoop itself is made from 1.75" x 0.188" wall DOM tubing with a reinforced mounting tab that locates off the factory upper shock mount. 2 additional mount points at the frame make for a strong design that looks great. There is a stainless steel "BDS" riveted to the shock hoop that matches the BDS dual stab kit and 4-link bracket nameplates.


Minor welding is required to add a support gusset to the factory axle shock mount and to add the provided steering stops if the tire/wheel combo installed gets too close to the shocks.
