Why Buy AST USA Shocks - The Four P’s

Besides tires, SHOCK ABSORBERS are the most important parts on your car.  They need to be perfectly matched to your springs, your driving style, and your car overall. 

AST PREMIUM SHOCK ABSORBERS offer superior performance in FOUR CRITICAL AREAS:

• Price
• Performance
• Piston size
• Pressurization

Before AST, there were constant compromises when shopping for shocks.  When you choose AST USA, you can have the best in all four areas and create a performance oriented package that you know you deserve.

Price

Consider what you get with AST products and the value for your money becomes self evident. All levels of AST shock absorber are hand built using brand new, custom housings. Even with the Performance Grade 4100 series, you are getting the internals of the 3 way shocks in a single adjustable (rebound only) coilover kit. Competitiors at or below AST prices simply do not offer the same high technology and features.

Performance

AST shocks are monotube design for a reason; they perform better.  When will you notice this?  Big bumps in turns and fast transitions on the track / autocross course are where true premium shock performance becomes evident.  Ride in or drive any car with this level of shock and you’ll know instantly why people buy them, they make the difference.  Other non-monotube designs on the market exist for two reasons:  comfort and cheaper manfacturing expense.  These are two things can do without when time on the track counts!

Piston Size

AST's monotube design translates into a bigger piston. When you put AST shocks on your car, you know that those big pistons can handle much larger loads. This translates directly into the ability to fine tune your shock. Other shocks that use twin tubes have much smaller pistons; and that means less ability to handle performance loads and less flexibility when it comes to adjustments.

Pressurization

All of our shocks are pressurized to a minimum of 175 psi with nitrogen.  High pressurization keeps the oil from cavitating around the AST piston.  Cavitation makes the shock ineffective, pressurization makes a consistent environment for the shock to do its job correctly with every stroke. Other lesser products (and even some more expensive ones) say they are pressurized, but they may be only
14 -29 psi - not something you need on your mind when approaching the next curve.

When you choose AST, you know that with each and every bump and hard corner, your shocks will be there to meet the challenge with superior design, pressurization, and value.
