Enhancing your GMC Sierra into a cargo and towing powerhouse takes a big step forward with 1999-2018 air ride suspension, aftermarket air spring kits that buttress your truck’s rear suspension so it can sustain up to several tons of additional load. Many increase load capacity by 5,000-6,000 lbs, so that your truck’s suspension won’t squat or bottom out in the rear when you’re hauling that extra-heavy load. The air springs also help to prevent loads from throwing the alignment of the body slightly off-kilter, which could cause the headlights to aim high among other problems. Sway while towing is greatly reduced, and 1999-2018 air ride suspension accessories give you the controls needed to adjust your air springs by increasing or decreasing the pressure inside.
