This is just a quick glance chart to give you a view of the different shocks designs on one page.

In our opinion, monotube high pressure gas units offer the best dampening power, performance, and handling. (the dark green section).

This does not mean you always need performance. For average driving, a twin tube low pressure unit is still a good choice. (indicated in the yellow section).

The AGX is a specific kind of unit for performance, and the only adjustable unit for cars we carry of this kind (indicated by the light green section).

Bilstein Sports - High pressure gas monotube design. 360psi to prevent aeration and shock fade. Sports usually (but not always) have a stiffer performance valving than the Heavy Duty units, and are recommended for vehicles with a lowered / performance suspension-springs installed. On shock applications, they can usually be used on stock height cars and trucks as well. These are great for performance, handling, and stability. (They are only available for a few specific vehicles).
