Here are some visuals from a drawing for reference, note there are 2 primary components; the air cup housing itself then the piston.



What Is A Coilover Air Piston Cup Kit?

A coilover air cup kit is a happy medium between actual air ride and static coilovers. In fact it takes the benefits from both, and for the most part leaves behind the negatives associated with each. Might sound to good too be true, but we speak the truth!

Air cups do NOT sacrifice performance like a traditional air bag , AND coilover air cups have the ability for instant height adjustment when needed.


How Does A Coilover Air Piston Cup Kit Work?

A aluminum cylinder with a internal piston sits on top of the coilover spring, replacing the upper spring perch. At normal “static” coilover ride height the air cup remains inactive, and is simply treated like a spring perch as the coilover functions normally. When a increase of height is needed (about 1-2 inches) in seconds you can raise the vehicle height as air pressure fills the cup chamber and pushes a piston down, in return compressing your spring and raising the vehicle. This is perfect for a track car getting out of a trailer, or a stanced car getting over a speed bump or up a driveway. You can sustain all the great performance features of your ISC coilovers, but have the convenience of air ride.
