Air Lift has released its heavy-duty LoadLifter 5000 (pictured) and LoadLifter 5000 ULTIMATE air spring series to support and protect Ford’s 2017 Super Duty F-250 and F-350 4WD pickups. LoadLifter 5000 (#57399), Air Lift’s heaviest-rated air spring kit, is specifically engineered for Super Duty pickups. The new LoadLifter 5000 ULTIMATE (#88399) for the Super Duty line offers all the benefits of the LoadLifter 5000, but with the addition of an exclusive internal jounce bumper, which provides added shock absorption and extra protection for heavy loads. The LoadLifter series works with the vehicle’s existing suspension to deliver up to 5,000 lbs. of load-leveling capacity and is air adjustable to keep vehicles stable, level and comfortable whether loaded or unloaded. Each kit includes exclusive Air Lift roll plates, which protect the air springs from sharp edges and increase load capacity up to 10 percent.
