AGX Adjustable Gas Shocks and Strut Cartridges are for the driving enthusiast. KYB AGX shock absorbers allow easy adjustment of the shock damping rate to tune the vehicle’s performance to meet the needs of the street, strip or track. KYB AGX Adjustable Gas shock absorbers are externally adjustable, so there is no need to disconnect or remove anything to change settings. The damping rate is selected with an external knob through a screwdriver inserted into a slot at the top of the strut’s piston rod. The KYB AGX shock absorber’s single damping adjustment changes the shock’s compression and rebound resistance at once. When you want adjustable high performance control, you want KYB AGX Adjustable Gas shock absorbers.
