Description

These springs fit inside existing coil springs to create a variable spring rate, leveling your vehicle and improving braking and handling under heavy loads. The air pressure can be adjusted to accommodate varying loads and conditions, similar to inflating a tire. Made from durable polyurethane, these springs support 500-1000 lbs. per set and operate in temperatures from -40 to 180 degrees Fahrenheit.
