Suspension manufacturer Air Lift Co. is releasing its installer-exclusive ProSeries air spring kit for the 2025 Toyota 4Runner.
Air Lift said the new product delivers up to 5,000 pounds of load-leveling support. The kit is not available for retail sale and is designed exclusively for professional installation.
“[The ProSeries helps] 4Runner owners maintain proper ride height, stability and control when towing or hauling heavy loads,” Air Lift said. “Built on Air Lift’s proven LoadLifter platform, the ProSeries system combines double-bellow air springs with upper and lower roll plates and ultra-high-strength nylon end caps for dependable performance under demanding conditions.”
The kit features adjustable air springs that provide 5 to 100 PSI and a 5,000-pound capacity. The bolt-on design requires no drilling to install.
The air springs help maintain a proper ride height during towing and hauling.
The company said, “Key suspension components, including air springs and hardware, are torture-tested to 1 million cycles on Air Lift’s hydraulic test rigs.”
