What is the benefit of a progressive spring design?

A progressive spring design means the spring rate changes as it compresses. This allows for a comfortable ride during normal driving, but stiffens up during harder cornering or when carrying extra weight, improving handling and reducing body roll.

Do these springs come with new bump stops or hardware?

This product includes the set of AST lowering springs. It is recommended to inspect your existing bump stops and hardware during installation and replace them if they show signs of wear.

What is covered by the lifetime warranty?

The lifetime warranty covers the springs against breaking. It's a testament to the well-built nature of the springs and provides peace of mind for the owner.
