Air suspension and trucks go together like peanut butter and jelly. Semi trucks have it. The new Ram 1500 just got it. Why? Because air suspension makes a truck ride better and haul better. The AutoFlex air suspension conversion should correct all these concerns by providing additional support and leveling out the truck and trailer combination. When the tow vehicle is level, then it can function to the full extent of its design. There is another benefit - a smoother ride. You may have read TFLcar.com reviews where we rave about the air suspension on the Jeep Grand Cherokee or a Mercedes-Benz GL550 and how smooth they are. Well, this conversion should have the same affect on the Super Duty. It should provide for a smoother ride for the people in the cab and the horses in the trailer. This air suspension system also provides trailing arms to better control the rear axle. This should show for better acceleration, stopping, and handling. In this series of videos, we take a new Ford F-250 and convert the leaf springs to air suspension. But to find out if air suspension is indeed better, we run a series of performance tests before and after we convert this Ford F-250 Super Duty to air suspension. In episode 5, we re-test the Ford F-150 after we've installed the air suspension from 60-0 MPH brake test and slalom cone test.
