How do I adjust the spring rate?

These springs allow you to control the air pressure, which adjusts the spring rate. You can easily alter the spring performance by inflating or deflating, just like a tire.

What is the weight capacity of these air helper springs?

These springs support 500-1000 lbs per set. Make sure that you never exceed your vehicle's gross vehicle weight rating (GVWR).

What temperature range can these springs handle?

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