2011-2019 Duramax LoadLifter 5000 Air Spring Kit (57338)

This LoadLifter 5000 underframe kit adds up to 5,000 lbs of load-leveling capacity to your Duramax Silverado or Sierra 2500HD/3500HD and works with most in-bed hitches. It eliminates squat, trailer sway, body roll, and bottoming out so you keep proper headlight aim and confident braking and steering with weight on board.
