Give your truck the extra support it needs with the Pacbrake HP10677 ALPHA HD Air Suspension Kit, built to improve stability when towing or carrying heavy loads. The heavy-duty air springs help level your vehicle by reducing rear-end sag and minimizing bottoming out, resulting in a more controlled ride. Corrosion-resistant components, including extra-thick end caps and reinforced internal support wires, are engineered to stand up to demanding job sites and harsh weather for lasting durability. Designed as a direct bolt-on system, the kit includes precision-fit brackets, quality hardware, and all the necessary installation components, making it easy to enhance your truck's suspension without permanent modifications.
