The KYB AGX rear shock lets enthusiasts alter damping quickly with a manual adjuster—either an eight‑position knob or a four‑position screwdriver slot depending on application—to increase corner damping rates up to 125% over OEM. Velocity‑sensitive valves respond to driving conditions to maintain tire contact and control on street or track. Consider KYB strut boot SB128 to protect the unit from road debris.
