What is the drop height for these springs?

These AST lowering springs are designed to lower the vehicle by 30mm in the front and 30mm in the rear. This change helps reduce the vehicle's center of gravity for a sportier look and potentially improved handling.

Are these springs compatible with my stock shocks?

These springs are intended as a direct replacement for your OEM springs and are designed to work with your vehicle's original equipment shocks. However, for optimal performance and longevity, it's always recommended to consult the manufacturer's installation guidelines or a professional mechanic.

What does the lifetime warranty cover?

AST provides a lifetime warranty against breaking for these lowering springs. This ensures that the springs are protected against manufacturing defects that could cause them to fail structurally over time.
