“Necessity is the mother of invention.” To some, this might just be an old saying…but to GE Engineer Claude Pemberton and Oldsmobile Toronado developer Don Perkins, this was the start of Air Lift Company in Lansing, Michigan in 1949. Post-war automotive fascination meant that families were crisscrossing the country in their cars, usually loaded down with kids and luggage—causing the springs to sag badly. With this in mind, Air Lift Company set out to build a suspension that would not only help support an overloaded vehicle, but would also improve ride quality and safety…a state of mind that Air Lift still adheres to today.
