Suspension Specialists since 1949

Air Lift Company has developed dependable air spring suspension products since our inception in 1949. Our original product, a rubber air spring inserted into a car’s factory coil spring, was created and patented in 1950. We’ve come a long way since 1949 and are proud to be a dedicated suspension specialist company.

Today, Air Lift load support products are sold worldwide and are engineered to fit over 540 vehicles. Our extensive product line offers air helper springs for trucks, RVs, SUVs, CUVs, and vans, as well as the most technologically advanced on-board air compressor systems for on-the-go air spring control.

Air Lift leads the industry in no-drill applications â€“ kits that bolt onto your vehicle’s frame, speeding the installation process. Our teams work constantly to bring innovative products to you and upgrade existing products with the latest technology.

Our Air Lift Performance division customizes full air suspension replacement and compressor systems for lowered performance vehicles.

All of our efforts are spent ensuring your safety and comfort by designing, engineering, and manufacturing the highest quality suspension products. We are a family-owned business based in Lansing, Michigan, and make your family and cargo’s safety our top priority.

Nascar Roots

The early years of stock car racing proved Air Lift’s air springs’ supreme versatility. Our products were widely used for twenty years by nearly every stock car racing team for twenty years, and our cars were among the top competitors on the NASCAR Grand National Circuit. We are proud of our racing roots and are committed to customizing our products for your needs on the road.

In the 1950s, Air Lift pioneered using air spring inserts in coil suspensions.

By the 1960s, we were already introducing sleeve-type air springs on pickup truck suspensions.

Then, in the 1980s, we provided air helper springs for motor homes and ambulances. Our constant ingenuity paved the way for street rods and lowered vehicles in the 1990s.

Today’s products are an evolution of Air Lift’s revolutionary development programs that apply the use of air springs in light truck and motor home suspensions. Air Lift has received the most awards in the industry from SEMA, recognizing our commitment to quality and innovation.
