2001-2004 GM Duramax 6.6L LB7 Air Springs
The 2001-2004 GM 6.6L Duramax LB7 is more than capable of towing and hauling heavy loads, but the rear-end of your truck can start to sag and give instability issues long before you hit your Sierra/Silverado's GVWR or GCWR. A set of aftermarket air springs can give you and your truck the handling and stability needed for extreme towing applications in no time. Easy to install, these air springs prop up the rear-end of your GM truck whole towing or hauling, bringing you back to a leveled stance while preventing sway and instability along the way.
