Best Selling Suspension for your Sierra

GMC Sierra Coilovers

Shock absorbers are a key part of your GMC Sierra’s suspension system, so any change to that system will work even better with upgraded 1999-2018 coil over and shocks installed. American Trucks sells shocks for the whole gamut of suspension modifications (or lack thereof), including 1999-2018 stock height shocks which provide the benefits of off-road or on-road performance shock absorbers when the suspension hasn’t been otherwise modified. 1999-2018 lifted shocks & coil overs are designed to provide a stable, smooth ride and good handling when you’ve got your truck standing tall with suspension lifts for additional tire or ground clearance. On the other hand, if you’ve dropped your truck’s suspension for a lower center of gravity and a more streamlined appearance, there are specially made 1999-2018 lowered shocks to support this modification, too. Finally, there are 1999-2018 shock accessories such as shock boots to help your shocks function right.
