KYB gas adjust shocks...

KYBs are a "digressive" design. As they operate through their range of travel, they get softer....Yeah. The initial movement is stiff but toward the end of the travel, they are soft...unlike a decent shock that is soft for small suspension movements but get firmer as the travel becomes greater.
To better describe, going down a slightly bumpy road, the KYBs want to skip off of the pavement while a Bilstein, Fox or Viking wants to soak up the small bumps but firm up when the road gets rougher.
The KYBs are often used with stock torsion bars. The driver gets the feeling that they are a great shock because suddenly, the car rides firm and gives the impression that it will handle better. Try driving over a brick or cobblestone road and report back if you still have your teeth.
