How do I adjust the spring rate?

The spring rate can be altered by adjusting the air pressure in the air helper springs. This allows you to make adjustments for varying loads and road conditions, as easily as inflating a tire.

What temperature range can these springs withstand?

Firestone Coil-Rite air helper springs are designed to work in temperatures between 180 degrees F (82 degrees C) and -40 degrees F (-40 degrees C). This makes them suitable for a wide range of climates and conditions.

What is the weight capacity of these springs?

The air springs will support 500-1000 lbs. per set. Be sure not to exceed your vehicle's GVWR. These springs help support the load, but the GVWR is the limit of what the vehicle can safely handle.
