A Suspension modification, often done by Jeep, truck, SUV and offroad enthusiasts is performed to raise the ride height of their vehicle. Suspension lifts (also referred to as lift kits or leveling kits) enable steeper approach, departure, and breakover angles, higher ground clearance, and helps accommodate larger wheels and tires. Due to the raised center of gravity, maximum safe operating angles are reduced and roadholding is often significantly impaired with a lift kit.

Kits can be as simple as lift blocks (spacers placed between the axles and leaf springs) and coil spring/strut spacers and extended shocks; to replacement control arms, trailing arms, and custom four-link systems. Suspension lifts also impact other factors, such as drive shaft length, steering geometry and brake lines. Legality is often an issue when installing suspension lifts, as many jurisdictions have varying laws on vehicle ride height and placement of lights and bumpers.

In 1978, The Boler Company, whose holdings included manufacturers of leaf springs and metal bumpers, purchased Hendrickson. In the years that followed, Hendrickson would expand into or acquire additional businesses in related areas—trailer suspension systems, auxiliary axle systems, springs, metal bumpers, and other heavy-duty components.

With sales of approximately EUR 1,301 million in 2018, SAF-HOLLAND Group is one of the world’s leading manufacturers and suppliers of chassis-related systems and components. Products range from axle and suspension systems to landing gear, marketed under the brands SAF, Holland, Neway, KLL, V.Orlandi and York.

Silent Drive Inc. has been in the suspension business since 1972. They are a family-owned and operated company that offers customized lift axles plus a variety of ready to ship lift axles for tag and pusher use, with their specialty suspension being the “Maxle”.
